I've always known Nu = New, it's used for Doctor Who and BSG as well. But, yea, I did think the reason for spelling it Nu was an Abbreviation for New Universe (Despite the fact that the "u" is rarely capitalized)
As for Chris Pine Trek, I switch up what I call it, I call it JJTrek and AbramsTrek as well as NuTrek and on rare occasions I call it Bad Robot Trek, The characters though, I almost always refer to as Nu... or sometimes as the actor+character, such as Pine-Kirk.

Where are we going? And why are we in this Handbasket?
