It seems like Apple should announce a release date here soon...
Then again, I guess now that they're doing digital distribution only, it'll take only a few hours to get from having a final build made to having it up everywhere on the app store, whereas before they'd have to print off thousands of DVDs with the final build, then ship them to all the stores, which probably made it take closer to a week.
Thus, Apple may not announce a release date until 2 or 3 days in advance, because they may not be certain that it's 100% ready until then. (It sounded to me like the GM still had some minor bugs... personally, I'm running Beta 4 and haven't noticed any strange behavior at all.)
1 - Huh? A 2 finger swipe in column view (the only view worth using) causes it to scroll back and forth through the columns.
2 - I don't use Adobe products, but I have used other apps which rely on scrolling for zooming in/out, and I have to say I enjoy "momentum zooming". If you don't like it, they you should be dragging instead of swiping... if your fingers are stationary before lifting, the view shouldn't drift.
