Absolutely! SEGA is the big one I really would like them to get plus it would be ‘organic’ 
.
Also in terms of volume Ubisoft makes alot of sense to me. They release a tonne of games each year, have a huge library and come with so many support studios that they can also assist Xbox studios in getting their games out in time cough.
If someone else acquires NetherRealm they should also go after Capcom to secure Street Fighter instead.
