I think we should wait until the acquired studios from 2018 actually release a AAA exclusive game (so starting this year). If they are received well and considered system sellers comparable to zelda, mario, god of war, the last of us etc then he should stay. If not then no because I would say Xbox would has not released a system seller since Halo 3. On a side note, I'm looking forward to hellblade 2 and avowed so hopefully they deliver!
