Activision is in bed with Sony for Destiny much like it's in bed with Microsoft for Call of Duty.
That's well known for a long time.
For Bungie, this works extremely well. The Xbox audience is already pretty familiar with their games and style, so it makes sense for the big marketing push to go to Sony's console.
The only thing that I've noticed, being an active member of Bungie.net, is that Xbox owners are really disappointed on the exclusive content for the PS3/4. There's a sense of betrayal, which I can somewhat understand, but Bungie seems oblivious to it, since it won't affect sales.
