Hello there Sonar732. Steel Beasts 2 a long way off and my understanding is that it will have less features than Steel Beasts Pro PE but will cost less. I believe it will be aimed squarely at the gaming market and as such different priorities will drive the development. As a tank simulation it will be very close to SB Pro PE. Take a look at this link:

Here you can see some of the planed features and the goals of the different products. SB2 is listed as “Entertainment for consumers” Hope that gives you a general idea of what’s coming. It’s about as much as I know.
