Konami has coughed up some details on the portable versions of PES 2008, which is being worked on by Konami's football studio in Tokyo.
The PSP game will share a lot of content with the existing PlayStation 2 game (and not the broken bits of the PS3 version) such as a wide range of tournaments and leagues.
Full Edit modes are also in there and Master League info can be swapped between the PSP and PlayStation 2 versions, as can League, World Tour and Cup Mode data.
On the DS side of things you'll get modes such as Exhibition, Penalty Shoot-Out and Konami Cup. Wireless features are also being used with a Network mode allowing up to four players to have a virtual kick about (if they've all got copies of the game). One-on-one games however can be played with just one copy.
Lookout for the handheld versions in shops early next year.
