Update on CliffyB's fps project that I found:
It's codenamed "Silverstreak", it will be PC-only, and he wants to use UE4.
Also mentioned returning "to his roots" and "the game that he cut his teeth on" in multiple interviews. Also, a few possible hints that his old Epic team could be helping out?

He runs the offical UT facebook pages, was commenting/promoting the recent 2k4ctf draft stream, and seems to be the only person at Epic who has a real passion for the series.
PS. "There's this thing that happens where stuff that was cool 10 years ago becomes cool again" - from his Joe Rogan interview 2 months ago.
