I don't think Rockstar would do that.
My whole point about hardware really is that I think MS benefits by being 1 year behind Sony now. Nothing takes advantage of the hardware fully at launch anyway, Sony's going to sell every machine they make regardless of whether or not another Xbox launches at the same time, and digital ecosystem lockdowns give every incentive for hardcore Xbox fans to wait a year to get better hardware than jump ship to Sony. The other advantage of being a year behind is that even unoptimized games where PS is the lead platform will play at least as good on 1 year newer hardware.
Mid-gen 2025 and new console in 2029.
The rumored handheld is on it's own path and just has to deliver S performance in a handheld, whenever that can happen. The next handheld has to deliver X performance which will be a long while from now.
With 32+ dev teams MS never really has to worry about support ever again. Like Nintendo, they can do whatever they want.
It really doesn't matter if MS can't do something to disrupt the market. If Ms just puts out a mid gen console that is a 10% or even 20% faster than ps5 pro but a year later even with the dev support they have it wont change anything. They need to bring out somethign ground breaking along with software that supports it.
