I dunno, Firaxis is pretty cool sometimes.
I just hope it works out better than Civilization 3 did. Honestly, Reynolds worked the design so well, just needed a few more things and it would've been perfect, but Civ 3, IMHO, pushed the series back as much as it brought it forwards. Culture? Cool. HORRIBLE CORRUPTION OMG? Bad. A host of other cool little things? Cool. Getting rid of the HP/FP system? Bad.
You can disagree with me, but I just had a lot more good times playing Civ 2 than Civ 3. Maybe it's been patched and has since become infinitely better, but, I haven't picked it back up yet, and I doubt I will.
