I could easily see them acquiring PUBG Corp.

Valve and EA, however, not happening. Both of those are going to cost A LOT of money that I'm sure will make Microsoft pause and really mull over, and both of those companies, particularly EA, are doing perfectly fine for themselves (Battlefront II controversy aside). So, I don't think they'd want to be bought out unless Microsoft blows them away with an incredible offer they absolutely cannot refuse.
