Well lets be somewhat realistic.
My biggest combo would be Eidos Montreal and Crytek. The first military shooter that employs the depth of Deus Ex a true military simulator where every decision shapes the out come of the game.
Sonic Team and Nintendo EAD Tokyo. Creating the first cross world game featuring both Mario and Sonic who get trapped and teleported to each others worlds. They need to find answers and get back home but how. Mixing the two biggest franchises and the two finest plat forming companies together.
Myst walker and Game Freak, over seen by Pokemon company Mystwalker and Game Freak combine forces to make the most in depth Pokemon console game ever made.
Square Enid and Nintendo. They had a joint studio and while I know Genius Sonority still works with Square and Nintendo still has some influence. After Crystal Chronicles it became apparent that Nintendo and Squares expertise combined is simply amazing.
BioWare and Nintendo EAD Kyoto (Zelda team). Bringing a Zelda MMO to the world the creators of some of the best western RPGs in the world are best suited to bring Zelda to the world.
I can think of another dozen studio combos from mobile phone developers to DLC Nes to full blown content.
