MoH - They've only JUST started doing modern combat. They can take this back to WW1 and even go back to WW2 Eastern Theatre.
If CoD and BF series did not exist, maybe. Competition from their side is too massive to dive back into a franchise that have not seen a release for years.
DS - They could easily crank out another 1 + DLC game.
Its as dead and as concluded as it can get.
Ultima - NFI
SC - again, could do a futuristic or historical feel.
EA got policy of online only as well as loot boxes and micro transactions everywhere.
The game does not suit this and can't be bent without runing it and they already tried - they are not going to try again-its EA, they'd rather kill studio and move on to murder another then release something they know did not work.
Ultima also isn't going to see anything new, Mortal Online is closest you'll ever get(given we're talking about the MMO Ultima, not the RPG one).
