I love Xcom. Its a great game. Its a Tactical Combat lovers happy place. Firaxis did a pretty good job with it and its expansion but has abandoned it and as far as can be seen has zero plans to update or even do the same thing in 'newer' technology.
If I won the Power ball Lottery...850 Million.?? I would buy the liscence from Firaxis and hire Paul to release it as
Xcom-Reborn ...or something along that line.
