I can't wait personally, I've loved NIN for a long time now, seen them live as part of their 'farewell tour' a few years back, Trent's music just really 'resonates' with me... I'll be buying Hesitation Marks for certain as I own all other Nine Inch Nails albums, for better or worse but even though I'll always love Pretty Hate Machine and Downward Spiral I can always find something to love about each album.
Oh and The Slip definitely counts as a release, they may have initially given it out for free but I bought the limited edition CD to support them - plus I wanted it, blatantly - but yes, it's good to see another NIN album on the horizon, my money is as good as spent on this already.
