Let me help! Off memory AHEM:
Flippin Pixels: A lot of the handheld team including the team lead Gary Richards, but there's confusion as his Linkedin says he's also at a company called BigBit.
Nyamyam: A few folks including folks from between Diddy Kong Racing, Stair fax Temperatures, Kinect Sports, etc.
Working on Tengami along with David Wise for the music!
Grant Kirkhope: Was at Big Huge Games until deaded, he's seemingly semi-freelance (he's I think a main contractor of Spark Unlimited, but he's still doing other stuff thank god).
David Wise: Freelance, now also working on Donkey Kong Country: Tropical Freeze muthu fuckas!
Gory Detail: Formed by Chris Seavor, and good bud Shawn Pile is also on board. Working on Rusty Pup.
Crytek UK: Was Free Radical Design, formed by the shooter team. The leads like David Doak and Steve Ellis flew the coop though. Norgate (composer) is still there.
Zoonami: Formed by Martin Hollis, also Ed Sludden (background artist on Conker) worked there, did all the art on Bonsai Barber! The team seems to be dead but most (sans Hollis) formed Otterly for iOS stuff...
Rhys Lewis: Was a programmer on the original Banjo, now at Retro!
Kevin Bayliss: Original designer of DK and Diddy himself! Left in 2005 for surprisingly a music career!
A lot of others are freelance like Mark Betteridge (studio head), and a few other composers (Loveday I think is gone).
Robin Beanland, the Mayless brothers, Craig Duncan are among those still trapped I MEAN still there.
Edit: Forgot about Eurocom, which housed a few folks from both Rare and Free Radical, one Rare person was someone who did the renders for DKR, who then did the multiplayer in Goldeneye Wii.
