April 13, 2005 - Several weeks ago, it seemed as though Nintendo was keeping busy filing patent after patent at the U.S Trademark and Copyright office. And for awhile, gamers everywhere were finding "gold" buried under the mass of technical jargon. Bloggers filled the web with theories, most of which centered on the Nintendo Revolution, the upcoming successor to the GameCube. Then all went quiet. At least for awhile. A quick search on the Copyright office website reveals Nintendo filed a trademarkon April 01, 2005 for Punch-Out!!.
Nintendo fans need no introduction to the Punch-Out!! legacy, but for those who don't know, it's as classic as Mario himself. Even today, Super Punch-Out!! for the SNES holds its own as a fantastic boxing game. So, what does this recent filing mean exactly? Depending on one's imagination, it can mean a little or a lot. A new Punch-Out!! title for the GameCube? Possibly. A Revolution launch title? Maybe. It may even hint at an upcoming Nintendo DS title. The only thing of any real certainty is that no one will know for a very long time. This is Nintendo, after all.
Stay tuned.
