i dunno how the DS sales are gonna skyrocket when there's barely enough supply to meet the current demand. The DS should get more publicity tho as you say. Thing is, the PSP and DS market are just so different that I don't think they overlap as much as you make it seem. Basically, I don't think the people that were seriously considering the PSP are going to immediately rush out and get a DS because of Pokemon. Anyway, we'll have to wait and see how the PSP price cut affects sales, but in April I'm expecting it to do just as well as the 360, which should have a good month with the release of the Elite.
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.
