From what I've read they where the creators of the og halo trilogy on the classic xbox. Halo was the face of xbox
Could just be a small punch in microsoft's face considering that they have basicly taken over what most people would have otherwise considered sony mascots in spyro and crash.
I doubt it was for destiny, it's because of their origins with halo.
That really doesn't make any sense for them to do, Microsoft doesn't care about Bungie, because they got Halo. Even if it was true, Microsoft got Spyro and Crash, Sony didn't get Master Chief, it's not much of a snub. Not too mention that acquisitions take weeks to months of negotiation, so this was likely happening during the same time as Microsoft was acquiring ActiBlizz. If anything, with slightly different timing, Sony's info could've come out first over Microsoft's.
Sure, however I'm fairly sure sony was aware that microsoft was trying to buy out blizzard/ activision. While the common man wouldn't know I'm fairly sure higher ups at sony knew, this might have been their response.
Besides even if it doesn't mean them owning halo wich was already a given, they are the company that made them good halo games. It's the company that put xbox on the map really.
Eitherway just my 2 cents, I otherwise don't see anything special in bungie.
