I'll keep saying this was a success for MS, but a disaster for the japanese devs, and not effective at all to stop the PS3.
Talking strictly of JRPG, XB360 can't say it was left out or unsupported, as it has 7 JRPG right now (counting SRPG which is a genre of JRPG), with more to come soon (IU in first), with lots of production value for the traditional JRPG ones (the SRPG are very poor).
Wii has 6 JRPG (still counting SRPG), but it's 1 year younger. Of course, because of that and the poor 3rd party support, most Wii JRPG are far lower profile and cost way less to make, but still they sold more than the XB360 ones.
PS3 has 5 JRPG, which is not so bad, except that the 2 good ones are all SRPG, which is a very niche genre, 2 are nearly H SRPG (even more niche than SRPG), and 1 is a very bad traditional JRPG (Enchanted Arms) that I usually do not count as JRPG.
The good traditional JRPG are still to come on PS3 though, but they will come soon.
With Eternal Sonata coming soon, in an enhanced version, this will make 6 JRPG for the PS3 this year. Keep in mind the XB360 is one year older. So this strategy wasn't really effective against the PS3, especially as FFXIII is still exclusive to PS3 in Japan.
