Konami has filed a pair of trademarks that hint towards possible Metal Gear arcade action in the future. The listings are Metal Gear and Tactical Online Action, and both are described as "arcade games, namely, amusement game machines, coin-operated video games, electronic game machines" in the filings. With Metal Gear Solid Touch recently arriving on iPhone, it looks like Konami is willing to put the franchise on more platforms than ever (except for, you know, that one).
Let's just hope that this Metal Gear -- if it ever becomes more than a trademark -- gets a little more TLC than that silly Silent Hill arcade game.
