I'm skeptical. Some of that sounds probable. But some stuff... Borderlands 3 on gamepass for instance sounds very unlikely. Borderlands 2 sold very well and no doubt 2K/Gearbox will want even higher sales, so unless Microsoft offered them an insane amount of money I really can't see them giving it away on gamepass.
Halo: Genesis sounds sketchy too. Wasn't Halo 5 supposed to be part of a new trilogy? Would they really just scrap that idea to reboot the franchise? Just sounds like a great way to piss off fans.
