If you’ve attended any of my class, it’s no secret that this is my tool of choice. I’d expect it to be released in June dur­ing the WWDC, but look who’s finally come to the show.

A slew of new fea­tures, among them will be the Brushes (Nondestructive brush, edge detec­tion & sup­port for pres­sure sen­si­tive tablets) & Adjustment Presets (Apply from Import, one click, cus­tom set­tings — see video) that pho­tog­ra­phers have been cry­ing for since day 1.

The biggest not-so-secret secret is 64-bit support:

64-Bit Support (requires Snow Leopard and Intel Core 2 Duo proces­sor) With Snow Leopard, the Mac can sup­port up to 16 ter­abytes of mem­ory, and 64-bit appli­ca­tions like Aperture 3 can take advan­tage of this larger mem­ory capacity.

Update: Macworld’s Jason Snell has posted an update note. For those who are as curi­ous as me, Faces data from iPhoto can be imported (thanks @Jason!).
