It's probably a good idea, just because so many gamers are already associating the title Final Fantasy Versus XIII with vaporware. I do, for one.
As spotted by GameChup , Amazon Japan has recently altered the listing for Versus XIII to say "tentative" next to the original title.
That apparently wasn't there before, so this implies that Square Enix is considering a name change, right? You may recall that Final Fantasy Agito XIII for the PSP was eventually changed to Final Fantasy Type-0 , so it's not like the publisher has never changed names for announced titles. Some time ago, it was rumored that Versus XIII had actually become Final Fantasy XV , although that speculation was shot down a little later. Then there's always the possibility that the project has hit the skids and Square Enix has no idea what to do with it.
Considering what has happened to Final Fantasy this generation, I wouldn't be surprised in the least if the latter explanation was the correct one.
