In a recent Gamepro interview, Hideo Kojima makes it clear that his aspirations involve more than just the Playstation 3. The Metal Gear designer notes that he eventually wants to develop for the Wii, the Xbox 360 (he's a fan of Gears of War, you know) and the "world-wide platform" that is the PC. "I want to do it. But our staff, especially the younger ones, don't so much like to work on the PC. If it was PC, we don't have to go into some crappy things with the first parties."
Going by Kojima's earlier steak dinner and movie analogies, we suppose he can now be interpreted as a rabid film critic wandering about town, randomly bursting into houses and demanding delicious steaks. Of course, PC gaming needs to fit in there somewhere -- is it like leveling up your own livestock, shortly before slaughtering it and eating it alone?
Read the interview and make your own conclusions. Watch out for Kojima stating that "MGS4 is actually for the PS3 only so far."
