The Legacy Collection, the first Metal Gear Solid anthology to collect titles of the series from four different gaming devices on one console, was officially announced only a couple of weeks ago. It has since been detailed in content (pretty much everything) and platform (the PlayStation 3, only).
What we have not been given is a release date or a price. Initial signs pointed to June 11, but with the official Japanese page for the game now up on the Konami website, it looks as though those reports were a bit off. Japan is slated to receive The Legacy Collection on July 11, priced at ¥7,980 (¥7,182 at the Konami Style store), which comes out to about $80.
To justify the price, the collection will include a 100-page art book. No word on whether or not the date and price also apply to the North American release of the collection.
