xbox is infamous ofr being overloaded with fps and putting no attention to the platformers and little to the rpgs
i think 2008 will change that
it has a good variety of western rpgs
fallout 3, fable 2(exclusive), too human(exclusive)(not full rpg but heavy rpg elements), and possible mass effect 2(likely exclusive)
for Jrpgs
the last remnant, infininate undiscovery(exclusive), and lost oddyssey(exclusive)
these titles may even go head to head with the ps3 white night chronicles and ff13
this will be a huge step for the xbox fully breaking into this genre
