I think they look more like warmachine colossals than a 40k model. I swear the blue one is a Cygnar model on a GW base and the red one could pass for Khador if it wasn't for the head.
This actually shows one of the biggest differences between PP and GW.
PP adds colossals to the game and you can use 1-2 of them (unless you are a crazy dwarf player) and for the most part, a colossal or a pair of heavy's are pretty much equivalent.
GW wants to add colossals to their game, so they do it in a way to add 3-6 expensive models...and lets not talk about balancing rules.
They do look pretty cool and I wish it was practical to play with multiples of them at the 28mm scale. It is too bad that they never made a larger scale (or smaller scale depending on how you want to look at it) game at the 6mm scale where using all these large models would be really practical.....
At 2000 points you can get 5 of these...assuming the Knight legions ignore the HQ+Troops thing (which I would not be surprised to see, kind of like the imperial armored spearhead).
GW is really confusing me with all these super large scale releases. Seems like they do not know what game they are making models for anymore. Is it a small scale tactical war game...is it a super walker skirmish game? Mixing the two together does not make a ton of sense since the latter pretty much invalidates the former (and really super heavies pretty much make troops useless). What is really confusing is the rules (and I am not talking about things like there is no balance at all, point cost between codexes are not even remotely equivalent, spooling out new codexes while armies are are still operating out of a dex that is 2 editions out of date). Wraithknight, Riptide are not that much different than a dreadnaught, but the former are MC and the later is a Walker. And then the Knight is a walker, when it is pretty close to the riptide. Doesn't make a lot of sense, should be all some kind of walker.
