Here's the flaw in that logic: JRPG fans don't have to cross over. The fans can simply lose interest. Just look at Japan from the start of this generation. There have been a number of JRPG releases, but they've all pretty much been on the 360. In 2 1/2 years, pretty much no one has bought a 360, and JRPG sales have plummeted compared to past generations. Where have all the JRPG fans gone? I think a lot of them have faded away. Based on sales, it's pretty clear the interest in the JRPG genre is at an all time low. And for the first time ever, the concentration of JRPGs have been diffused over multiple systems, which IMO is weakening the genre.
This whole situation in which MS pays for JRPGs is certainly not helping MS and it's certainly hurting Sony, but the most nefarious consequence is the demise of the JRPG.
N.B. I'm not saying the genre is dead, but with DQ on the DS and FFXIII on the PS3 and everything else on the 360, the genre has become more niche and less profitable than ever.
My Top 5:
Shadow of the Colossus, Metal Gear Solid 3, Shenmue, Skies of Arcadia, Chrono Trigger
My 2 nex-gen systems: PS3 
and Wii 
Prediction Aug '08: We see the PSP2 released fall '09. Graphically, it's basically the same as the current system. UMD drive ditched and replaced by 4-8gb on board flash memory. Other upgrades: 2nd analog nub, touchscreen, blutooth, motion sensor. Design: Flip-style or slider. Size: Think Iphone. Cost: $199. Will be profitable on day 1.
