I just got in touch with Zoink Games and have some info to share:
The game runs in 480p and 16:9, they're unsure about Dolby Pro Logic II and the framerate at the moment. It seems to run in 60 frames in the NTSC build, but again, they're unsure.
The game has progressed graphically since the beta build:

Described as much crisper and with better lighting now.
New screens should be out in a few weeks.
All the voice actors from the Xbox version will finish their roles.
The Voice Cast list I was given is:
Jay Sopp (as Dr Samuelson)
Shelly Reynolds
Jen Taylor
David Scully
Gary Schwartz
Dex Manley
Nigel Neale
And the roles of Zoink and SnapDragon specifically are that Zoink does the direction, art, and music, while SnapDragon does the programming, as I expected.
And that's it!
