Gamespot today has a post that could make the “What console should I get” question a bit easier to answer.
During this generation of consoles, the PS2 has been the RPG’ers platform of choice. The 300lb Gorilla that is Square-Enix has kept a majority of their RPG’s on the PS2.
Now there is speculation that future installments of the Final Fantasy and Dragon Quest series’ could be coming out on both the PS3 and 360.

“TOKYO–In an interview with Reuters, Square Enix president Yoichi Wada disclosed that his company is considering releasing new installments of its Final Fantasy and Dragon Quest role-playing series on both the PlayStation 3 and Xbox 360. “We will decide by E3 in May [2006] as to whether to release them on both the PS3 and Xbox, or just one platform,” Wada told Reuters.

For the most part, both Final Fantasy and Dragon Quest have been exclusive to a single platform. Both series made their debut on Nintendo’s NES in the 1980s, and they continued to be hits on the SNES. However, Square defected to Sony Computer Entertainment’s camp in the late 1990s, and the primary Final Fantasy series became exclusive to the PlayStation and later the PlayStation 2. Enix also shifted its Dragon Quest series to the PlayStation in 2001 before merging with Square in 2003. The series then shifted to the PS2 with the 2004 remake of Dragon Quest V and Dragon Quest VIII, which just shipped in North America”

If this “rumor” turns out to be true, it would hurt the Ps3 a lot. However the way Sony has been behaving lately perhaps that not such a bad thing.
