Well, Abrams tank is only a bit longer and wider than a KV-2 (which is much higher), yet the price for the KV is the same as for all other WW2 sets, while Abrams is twice as expensive.
Now don't get me wrong, I'm not saying it's expensive - just thought that I'll give you a small update.
It seems that Zvezda has set up a page for this new game - Hot War - and they did it quite a time a go, judging from the dates:

- BTR-80

- Russian infantry

- American infantry

I really like what I see, though this double pose in the American set is a bit disappointing.
