343 and the Halo franchise is owned by Microsoft still, but Bungie bought their independence about 5 years ago, and is now working on a semi-MMO Sci-Fi series of games for Activision as part of a 10-year contract. Just google for "bungie activision contract", and "bungie destiny game" (or see the wikipedia article).
So, uh, 1/3rd of your wish is granted.
I could have worded that better. I'm hoping that through some cataclysmic cosmic miracle that MS will let 343 and Halo go and they would be merged back into Bungie.
So yes, 1/3 is fulfilled.
