D3Publisher will be offering six previously UMD-based games on the PSP Store later this year.
Puzzle Quest, the excellent PSP blend of puzzle and RPG that we waxed lyrical about back in early April 2007, leads the charge.
The other titles on offer will be Dead Head Fred, Cube, Practical IQ, Beta Bloc, and Super Pocket Tennis.
Prices are from GBP 7.49 upwards. We expect Puzzle Quest to be at the top end, although nothing has been confirmed.
Sony Japan recently announced plans to implement a true PSP Store - which is to say games downloaded direct to the handheld rather than via PC - this autumn.
European plans are yet to be set.
