Wherever he goes the magic will follow, and it'd be nice if he was the ultimate boss like he was at id Software.
It's quite arguable that the best time for id was back in Romero's time, through Quake 1. Carmack was an excellent steward technologically, but from a business standpoint I think they were far outstripped by Epic in terms of being a business based on technology licensing.
Sadly they were also outstripped by Epic in terms of games. Id didnt really have a hitgame for a decade while Epic had the hugely popular Gears of War series and their success with Unreal was on par with Quake.
While i also believe that Ids best time was in the 90ies when Romero was there, its not that he made anything noteworthy since he left.
