Here's a summary of the listed release dates for Prophecy Advance. These do seem rather credible, though things are always subject to change. Keep in mind that these are the shipping dates. You'd get the game from an online retailer the next day if you paid for overnight shipping. Most stores would get these one to three days after the ship date.
