If this leaked internal listing is legit, it looks like HP’s TouchPad will be coming to Wal-Mart for $599 for a 32GB model. We heard that it would be $699 earlier, and likely that price will still exist for the 64GB version. Will there be a cheapie one for $499? No word. We’re pretty sure it’s going to hit in June, though, so stay tuned for further leaks as the launch date approaches.
