We're not sure why Sony chose to announce the collector's edition to the best-selling PSN title of all-time by hiding it four minutes deep into a promo reel, but that's what happened earlier today in the video you can see below.
Unfortunately, the reel doesn't give us any information on what exactly will be included in this collector's edition. It doesn't even say if this will be a physical, boxed collection available in stores, or if it will be a PSN download.
If it's the former then color us excited to see what sort of goodies might be included. If it's the latter, then you can probably expect the game to come packaged with the official soundtrack and probably some XMB skins and other assorted digital doodads. We'll keep our eyes peeled for more information on this. Hopefully now that the cat is out of the bag, Sony will let us know what we can look forward to.
