Yeah when it comes to Smash DLC, possible future DLC seasons, idea of AT promotions, Hitagi, etc. I'm definitely taking a "wait and see" approach. If we get some cool characters, great, if Sakurai promotes Isaac to be playable, Sakurai will forever be awesome in my books, if we get lame characters, then eh, I'm already used to disappointment at this point after witnessing Lyn, Shovel Knight, and of course Isaac being sent to AT hell (again for a couple of them).
At this point the thing that's hyping me the most is that according to some early tier list predictions, all the characters I'm interested in playing are apparently atleast good, with some being really good. Megaman, ZSS, Simon, K Rool, and even Zelda! It's also nice to see that Bayonetta and Cloud might not be stupidly OP anymore, so I can play them and maybe not feel bad about it. Of course this stuff is really early and before the game has even been released so it probably means diddly **** but it's promising to see for now I guess.
