I doubt it. Each year there is less and less focus on hardware at WWDC. I expect Apple to do another 'almost the whole range' update / launch in the autumn like they did last year (based on Tim Cook's comments earlier this year). They'll launch the new 'pro-model' (presumably a MacPro) then.

Hate to break it to you, but Aperture as we know it is probably going away.
Apple has happily ceded the pro-app market to Adobe. Why would they bother throwing money at Aperture for the small (and constantly dissatisfied, see the complaining about the recent Adobe CC announcements) pro/prosumer photography market.
I'm hoping the huge gap since the last significant iPhoto / iMovie update means they're doing a major (read: post-ipad) overhaul of these two. And, since they added a bunch of Aperture like brush features to iPhoto on iPad, i expect the next iPhoto to be an amalgam of iPhoto and Aperture.
