Should any fan of the FF series be worried about FF XIII?

^ Sales are subjective?

I was refering to the "must be doing something wrong" part. For all it matters I like FF8 more than FF7. So yes, it's subjective.

Yet 8 sold less than 7 wich means that something about the game turned off fans of FF7. And thus, Square did something wrong with it.
