It hasn't been announced yet but I'd imagine looking at the screenshots that if your computer can run Civ V it can probably run CiVI.
means, stil no 64 bit support and so no support of multi cpu and more ram

same as Civ V and grafic like BE means, simply another squeeze out to make money.
nothing essentially.
So I don't expect that the engine is more intelligent that the stupid in Civ 5 and BE, and when all is to get by Steam only, then it is for me a reason to wait long time until I maybe buy it and check. Not worth to spend big money.
