Just gonna throw this out here; CT is the only time I've ever liked Toriyama's work.
I'd agree with the general assessments. Getting a good reputation for JRPGs would be a point in the 360's favor, but ultimately it doesn't seem like the kind of genre the game is geared towards. It's more likely the important 360-based RPGs will be more the traditional western style; as KOTOR and Jade Empire were highly regarded and successful on the original X-Box, so things like Mass Effect are likely to be on the 360.
