According to this site, a new Neo Geo handheld will be coming out, the Neo Geo X, with 20 built in classic titles as well as a memory card reader.
Blaze, the company behind the atgames handhelds, will be releasing the Neo Geo X, officially licensed from SNK. It will include an AV output, to display games on your TV. No definitive list of included games is available yet, although metal slug, king of monsters, and the fatal fury series is mentioned.
My personal take on this will all depend on the price, how well it emulates the games, and if it will play games from an SD memory card. We'll see how it plays out. http://www.highdefdigest.com/news/show/Sam...his_Spring/9032
