Yeah I know, something that's not E3 related. Still, a while back I posted that the Pokemon U.S. National Championships were being held this year at the Columbus Convention Center in Columbus, OH. I recently found out that registration is now open for anyone wanting to participate in the Pokemon TCG, Pokemon video game, or Pokken Tournament. The championships are being held from July 1st through July 3rd and while I'll likely have to work two of those three mornings and won't be competing anyway (I'm nowhere near good enough on any of those three to get anywhere), I still plan to try and hit up the convention center after work on the 2nd and 3rd, and most of the day on the 1st to check things out.
To register and for more information, check out the Pokemon U.S. National Championships website.
