Whilst i don't think this is the end of NIN, i do think this'll be the last new NIN for awhile...at least until TR has someone he wants to say/do with it. The last 3 EP's have been freaking solid, each in their own right, whilst catering to many different tastes and have been many fan's best NIN material for some time (not to say stuff hasn't been good, just not THIS good for awhile) so i except they'll take another break after the tour to work on the other mountains of projects they have...but they will be back eventually.
