Checked PS Store, it's now there at $50. No details yet on how the DLC characters will pop up. Hopefully they are free. And true to the fears of many fans, there are name changes.
1st Story Trailer detailing characters and plots of the first three seasons.
I'll wait until every DLC character is available and after Stardust Crusaders has done its televised run. For the rest of TAY, enjoy the alright fighting game!
