If the app store has a 'closeout bin' I bet that after Log X is out for several months you'll be able to find 9 for around cost just so they can clear out their inventory. "Last year's model" type of deal.
Thanks. I thought the release of X was just around the corner. . .a month or two away. . .at least that's what I have been reading on the Internet. That was my guess anyways. . .nobody seems to know for sure.
