Are we sure 6 will be more like 5 than 4?
Probably, it'll take at least one turkey (and maybe even too) for 2K to realise what they did to the name Civilisation with 5.
I'm sure very few people who actually bought 5 because of the name will want to throw their money at 6 until they have proof positive it's good. And very few of the casual players of 5 are even around, never mind coming back for 6.
