Will the cryengine 3 come to the consoles this time? and will crysis 3 run much smoother in single player and multiplayer?

??? Cryengine 3 has been on consoles. Crysis 2 was developed using it, and the original crysis was brought to consoles with CE3.

Do you mean something like SDK? I think that kind of things are PC exclusive.

About it running smoother, on one side they want to push the graphics on the consoles a bit more but on the other side now they should be able to handle the engine much more efficiently so... Anyway don′t expect anything over the 30 FPS mark.

Not sure I understand your question, Crysis 2 was made on CryEngine3

They are pushing the graphics a little more on all platforms
