It's pretty obvious that the 360 is going to be the console to own for WRPGs since what happened with PC FPSs coming to consoles is now starting to happen with WRPGs.
For example there was this press release about two new RPGs coming to PC/360:
dtp announces new RPGs at Leipzig Games Convention press conference – Broaden impact of adventure games worldwide
"Hamburg/Leipzig, Germany: August 23, 2007–dtp entertainment AG the Hamburg/Germany-based publisher today announced at its press conference at the Leipzig Games Convention 2007. That the company is taking a more important role in the international games business.
Two major announcements mark the course to an expanding portfolio covering multiple genres. Being released in 2009, two new million dollar development budget RPG productions are going to await the gamers’ interest: One of them, an action RPG, is being developed by the Frankfurt/Germany-based team Deck 13, which earned international acclaim for its adventure game releases“Ankh” and“Jack Keane”. The second RPG project is being developed by a well known Belgian team. Both games are being released on PC as well as on Xbox 360. Further details will be announced in the upcoming weeks."
Add to that the fact that CD Projeck is rumored to be porting The Witcher over to the 360 (they had a job ad for a 360 programmer) and another PC developer 10tacle is bringing Elveon to the 360 as well. Add to that Mass Effect 2 and 3, Fallout 3, Jade Empire 2 (heavily rumored), Fable 2, Knights of the Old Republic 3 (heavily rumored), Too Human, and others and it makes a pretty compelling lineup.
As far as JRPGs though the 360 will likely end up getting slightly less than the PS3 and significantly less than the Wii. The reason being RPGs are selling in enough numbers to justify the development costs of the 360 and PS3. It's likely though that the 360 will get some very good exclusives simply because Microsoft will continue to pay for them as they still try to gain marketshare and mindshare in Japan.
So it'll likely go down like this:
WRPGs 360 > PS3 >>> Wii
JRPGs Wii >>> PS3 > 360
Still though that's a lot better for the 360 than during the Xbox 1's lifetime.
