Oh god, I pray that these are gonna be coming to the US. It wouldn't be very hard--just change the Japanese names to American. Freezer to Articuno, Sleeper to Hypno...how hard would that be? Seriously.
And y'all are right. The Pokemon shirts now a days, if you can even find them in adult sizes, are too...well, cluttered, for one, and too kiddy. I like some of the ones that were on Pokemon Center, but these blow them right out of the water.
I'd so buy the Mewtwo and Cubone shirts, and wear them to league every weekend. I swear. XD
The price is kinda bad, though. Yikes.
But, I do think this is a very, very good move. In my state, the tournaments very, very rarely have over 10 Juniors--heck, they usually don't even have top 2 or 4 play off. 15 Seniors is rare, and then the Masters are usually in the 30's or so. So, yeah. Just judging by my state, this would be a great move. I hope it'll be coming to the US.
And, if not, there's always Ebay to get a hold of these. XD
