There will be certainly a 64-bits version of the game just that the Havok part may only be 32-bits.
Doesn't work that way. The program either is or isn't 64 bit; if you try and do half'n'half, you WILL break something.
not really convinced of that (hopefully not!) cause this would mean that the current things implemented (with the few things not yet in) are pretty much final...and a hope really thats not the case, cause right now, the game does not convince me at all...
FYI: we don't have everything at the moment, not even close. Tactical battles, magic system, diplomacy... and that's just what I can come up with off the top of my head. And there are other features which are 'in' but not used (quests are placeholders; city building has the code, but not the data to drive some extra features).
