I can still see that Sakurai taking on GS4 joke created a big argument. Well, all I want for GS4 I want it to be developed by Camelot and to have the same characteristics that GS1 and GS2 had (and for the love off god, I hope it doesn't have points of no return). I wouldn't mind other companies to help, however, the ideas for storyline, playability, characters, maps, dungeons, puzzles, etc. should all be made by Camelot and the other companies could help to make those ideas come true.
Also, if Sakurai would make GS4 storyline, we would have Dark Isaac and Jenna/Mia with a pole-staff dancing as their side taunt.
