Well, that's what I'd like to happen, but it probably won't....

,...still, I can dream....
Anyway, if this is true, then the tide has well and truly turned. This represents a hug marketing coup for Nintendo. SEGA was the first to relent, closely followed by Capcom and Namco, and now SquareSoft has joined the fray, well, who knows what may happen, but excpect developers in their hundreds to flock back to Nintendo. Now, Nintendo has four of the worlds top five developers tucked under their belts. (SquareSoft, Rarware, SEGA and Nintendo themselves, the fith being Bungie, which Microsoft blagged.)
On another note, perhaps it might attract back developers who push the GameCube away, because they got their hands bitten with the Nintendo 64, such as Konami. (Metal Gear Solid for the Nintendo GameCube, anyone?)
Also, his may kill off the 'short, but sweet' stratergy that runs around Nintendo at time of writing. With SquareSoft, and the influence that it brings to attract developers back to the Nintendo GameCube, relieving the games drought, Nintendo may have the time it needs to construct it's revelatory videogaming epics. We may yet see a 70 hour, realistic Zelda, and a humongous Mario game, before the Nintendo GameCube goes to the Great Attic of Forgotten Games Consoles in the Sky.....
