Well, I think I'll put in my 2 cents here too, now that we have something substantive to talk about and look at. My initial impression is disappointment in the fact that the White Dwarf does not mention our troops! Given that the new book is coming out in just a few weeks, we can safely assume that there is no "part II" to this, where our rank and file are featured. I was really hoping for at least one new infantry option. I'll wait until I see the new book, but I'm really hoping that we see some improved stats/lower costs/new abilities in our basic core infantry. This is at least hinted at with the different colored crests on the Skinks shown. Some of us don't like playing a monster-oriented army. Sure, it can be a nice option, but it's repetitious and as already said by others, with the cannon rules the way they are, it's usually a poor strategy. I really miss MSU...
I have to wonder at what, if anything, will happen to our existing troops. I'm concerned that Krox and Skrox options will be gone from the game. Just a hunch mind you, but given that GW lost the argument against the Croc-Ogres in court, I have been imagining that they will just say to heck with it and kill the competition by excluding the troop type altogether. Hopefully just a paranoid delusion on my part... I'd rather find out that the Krox rules have been fixed so that they are viable not only as a Skrox unit but also by themselves in units of 6 and 9.
I'm also curious as to whether we still have chameleons anymore. Seems unlikely that GW would not mention certain troop types at all in WD. Equally, I'm concerned that WD makes no mention at all of Salamanders and Razordons. We are all expecting the Sallie to get a nerf, but with all these new monsters would they really leave the old ones in place? Is WD marketed just to existing players? I would think that if the goal was to generate excitement about a new army and build the fan base, some brief mention of the other parts of the LM army would be made somewhere. Call me crazy, but these are my primary concerns.
Now, on to the new models:
Carnosaur - I personally didn't like the old one (and hate "finecast"), so this plastic kit seems like an improvement. Not psyched about the cost (holy cow!), but if it's really well designed (rules-wise) it will be worth buying. Kroc-Gar seems the most impressive configuration, which I'd use for the generic Old Blood since my group doesn't generally allow special characters in games. I am bummed that they made all 4 options for building it use the same hind legs. That's incredibly boring.
P.S., The fact that a Scar Vet can ride one could be very cool, however does this mean that the horned one is gone? I was sculpting one, so I hope not...
Troglodon - I like the weirdness of this model. If it's useful, I could see owning one. Again, bummed that it uses the exact same hind legs and pose as all the other Carnosaur builds.
Bastiladon - great looking dino, and glad to see an Anklosaurus in our ranks! The howdahs (solar engine/ark of sotek) however, look like crap. Very awkwardly stuck on. What a pity. The snake shooter especially...god awful! Sounds like something goblins or skaven would invent and has no place in our army, IMO. Not to mention, again, how bad the models look with those poorly conceived howdahs. I am hoping, against all hope, that I can field a Bastard-don without anything on its back. Yeah, good luck with that...
Terradons - I liked the new heads and the rock carrying models are long overdue and look o.k. to me, but I am not a fan of the new wing design at all. I am hoping that they look better from some other angle. They remind me of butterflies. Skink Chief and Tic-taq-toe variations are o.k., but only if the underlying terradon is nice looking. Probably a pass, and stick with the older models.
Ripperdactyls - did someone at the Studio have a brain fart? This has to be the dumbest unit name in the history of Warhammer!

I do like the way they look, and hopefully they will have a use taking out enemy cannons so that all these other monsters have a chance to do something other than die (see above, also also this feeds into my speculation that Chameleons will be gone). But that name! I will have to just call them "rippers" and leave it at that.
Tetto-ekko - very nice, much needed. Blurry picture, so I am not going to critique the model, other than to say that the conversions I've seen here have been pretty damn spectacular, so this had better be a fantastic model, or I will just make my own as others have done.
Skink High Priest - love this figure, it's a must-have, but for the $20 price tag. Seriously? $20 for a single small figure??? I'll wait for some to pop up on eBay, thanks! I cannot condone, participate in or encourage such thievery with my wallet.
Gor-Rok - looks like a gorilla, not a fan. Methinks GW is trying to compete with Avatars of War here. It's just not working for me though. I'll have to see a few more examples, maybe better painted, but even still, it's so easy to convert a decent looking Old Blood on foot and make it look better than this. Pass.
My 2 cents.
