Gamestop has listed the Metal Gear Solid HD Collection for pre-order, and have even been so good as to add a price and release date to the listing. Whether these are just guesses on behalf of the retailer or whether they've now released information we're not supposed to know is yet to be seen, so for now presume these are wrong until confirmed.
With a release date of the June 5th and a price tag of $39.99, the collection may be in our hands slightly quicker than expected. The $39.99 tag puts it into the same price bracket as the console version when it launched, although by June the older version is likely to be much cheaper. It's also worth remembering that the Vita version of the collection doesn't come with Peace Walker, which is a huge disappointment.
If you want a couple of great games on the move, you can't really go wrong with this set. Personally I'll be waiting to see a price drop.
