The fourth reprinting of Phoenix Wright was supposed to ship on the 25th, but NCSX says that it didn't, and that Capcom told them to wait for Aug 7 or 8. I'm guessing Capcom decided to stiff NCSX, since they already know they want them, and sent the whole batch out to the major retail chains instead. The last reprint batch showed up in small numbers at EB stores in Canada, at least.
I'm guessing Artimus lucked out and got there right when they put their single copy out on the shelf.
