Texas Showdown doesn’t exist anymore (unless they brought back the name), it’s Showdown Championships and it’s done as part of the anime convention Planet Zero hosts.
However, if somebody else in Houston picked up the name and is running oh holly FUCK!!!
The game lineup is really freaking weird. I’m actually glad KOF finally gets put into the line up. Other the KOF and UMvC3 the rest of the games I’m kinda indifferent.
EDIT: I just looked up the anime convention Anime Matsuri http://animematsuri.com/ and sure enough it’s on the same date for the tournament, and Showdown Championships is part of there lineup. Some big names have started to come back to the SC series so meh you never know.
