In case you missed it, here is the announcement of Metal Gear Arcade at E3. Having seen it now I see that they are planning on a worldwide release with this one with Japan coming in first so you will be finding it in US and European arcades down the road. The reason I emphasize this is because initially it was unclear as to where it would go based on info I read on websites prior to seeing this video. No word on when or for how much yet but at the very least this is yet another arcade title to come along this year that has players talking about in places that do not focus primarily on arcade titles.
I have also added this to our master release list for Arcade titles in 2009.
