I don't know how many Suikoden fans we have on these boards, but I'm a certified addict. For anyone else like me, a Japanese retailer apparently listed Suikoden VI for PSP and then quickly pulled it. Here's the "source:"

A few months ago, I would say this rumor had no chance to be true. I figured the game would go to the DS, Wii, or PS3. But with the success of Monster Hunter and the PSP's resurgence in Japan, I think Japanese devs are getting excited about the PSP these days, so this would make sense.
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.
