Personally i think there are already a few series that can really hurt FF status in the JRPG world, Lost Odissey is one of them, this game is utterly awesome, i'm loving every moment of it, but it does need some inovation since it has a few cliches that are common of JRPG's.
But what can really hurt FF is the Persona Series or one that comes from S-E themselves, KH. That series if it continues to grow like KH2 did from KH1 I can see many, many FF followers move to that series (in my personal opinion KH2 was way better than FFXII).
