Activision's just announced the lineup of development studios that will be backing the game up as Shrek the Third makes its multi-platform launch in May - just enough time for you to see them movie version when it hits theatres this March.
Here's the developers:
Shaba Games is handling the console release (Xbox 360, PS2, Wii).
Vicarious Visions is handling the DS and GBA releases.
Amaze Entertainment is handling the PSP release.
Beenox is handling the PC release.
The game will release on almost any platform except for the Playstation 3. Why? I have no idea...
