I don't see EA selling it. Sounds like Garriott is bored. But, I also do not know how much $ he has to offer.
Also I did a search to see what games EA has sold in the past. The results are acquisitions, not divestitures.
Personally, I'd be more hype to see Raph Koster in charge of the UO team at broadsword.. Since SotA I don't trust Lord British nor Starr Long.
Edit: the only way u see garriot back on UO is if he gets a licensing right for the web 3.0.. he badly wants to get in on that web 3.0 crypto MMO and UO would be the best choice possible at the moment for garriot (he fail his last 3.0 project before it even crack out of it's shell)
EA were notorious to buy studio and shut them down (killing the competition) while keeping the license/game alive (in a worst state)
And no way on earth Garriot has the money to buy Broadsword.. BS just inherited their third MMO the failed "bioware" Star Wars.. All he talks now a day is the web 3.0 MMO he badly wants his 3.0 MMO and UO would be perfect for that and EA ain't the company that scares away from bad reputation decision.. like creating their own EA crypto Token for the 3.0 on games like UO (another version of UO made for 3.0)
NCSoft were notorious (still are) for closing game.. look at tabula rasa and many more recently (ex: wildstar) if they don't 1000% profit the first year.. they shut it down type of stuff.
there people who have ran uo last 12 years have ran it in to the ground. he needs to tack over and fix stuff. lot of boters will be mad owell. then had there shoot to run it right and then ran it like it was there piggy bank. and there keep doing it to theres noting left. let 4 people run housing in all uo yea thats fair lolllllll
