I'll definitely be playing this.

Also, with regards to the whole "I'd rather they just make FFXV" thing, perhaps they are making an intelligent move and doing this in order to get a better feel for exactly what people are after before they jump into making FFXV. If they continue with three games per generation, they'll want to finish off the PS3/360 generation with a really good one. Especially due to not wanting to have three games in a row panned.

Oddly, I recently read on IGN that the reviews for FFXIII were generally heading towards good while in Japan they were much worse. It's a good read, the article - something like Japan in Decline or something.
