Here's another thing to consider, especially if you're an Xbox fan:
MS are spending huge on building up their internal studios in order to have a steady cadence of product for Gamepass, what that means is they will simultaneously be looking to spend less on paying third parties for exclusives. Now this isn't to say that they will never pay for exclusives, just that they will obviously be way more discriminatory in terms of what they need, what they pay, and what they consider valuable to their ecosystem.
The point being that the days of them paying $100m for an exclusive window on a Tomb Raider game are long gone. Which has to be a big consideration for SE as Sony are likely not going to be interested while they have a directly competitive first-party offering in Uncharted.
Think about what that means for Deus Ex, or Thief, are MS really going to want to spend big when they've basically bought most of the other WRPG developers? Are Sony going to make an equivalent bid especially while their push into PC publishing seems to be spearheaded by porting former console exclusive IP?
Market changes means IP values fluctuate, and this huge consolidation push is causing major ripples across the industry. Truth be told I'm not sure whether the market seems welcoming to legacy IP at this point in time due to the amount of competition.
