That mythical FFVII full remake they refuse to make would haul in millions if not tens of millions of unit sales globally. I personally do NOT want an FFVII remake, I do not think they could do the game justice, but such a game could potentially be a system seller. Just announcing such a game would probably up their stock price and reinvigorate the company in various ways.
I wonder if that rumor that they've renamed Versus XIII to Final Fantasy XV is true. The game in the videos looked pretty good, but there have got be a lot of bad reasons why that game basically went vaporware.
