User blog:Fujiwara No Mokou/Should I get it? + More questions.

Is it worth it to buy the new DLC characters right now? I dont know if I should. Also, does anyone know how big the sm4sh update is? Also, does anyone know when all the characters are released? Also, should I buy both the 3DS and Wii U characters? I don't have a Wii U, but I might get one. I only have a 3DS right now and if I get a Wii U later I don't want to pay for it again.

I needs opinions! :S
