You know, this could be your chance to play some newer stuff - you'll have the chance to experience id Tech 2, 3 and 4... after spending so much time with their primitive progenitor :P

But yeah, the last "proper" Quake game was Quake 4. Which would mean that then ext one would have to be 5... but nowadays numbers are often dropped (e.g. Doom 4 was simply named Doom), so the fifth Quake might never actually be called "Quake 5".
