 Rumours regarding the project state that the original Quake game is getting a "revitalised edition" with fancy new visuals and other improvements though, this has yet to be confirmed officially, so take it with a grain of salt. 

That being said, it looks like that a big Quake announcement is coming and QuakeCon 21 seems to be the perfect place for that.
