John Romero has worked on a ton of titles, being one of the founders of iD software back in the day, designer of Doom, Quake and the like.
According to the Community Manager, they are developing
a strategy game. That really wasn't on my list of guesses (at least not very high up)
John Romero's wife Brenda (also a game designer) did some writing on the Jagged Alliance series back in the day, but was more involved in the "Wizardry" series of RPG's (also developed by Sir-Tech, same company that made Jagged Alliance).
The two games that "Romero Games" has released this far has both been mobile games, which does not really lead to suggesting that this might be a game in the Jagged Alliance / X-com mold.. but we'll see
