how much will 2.0 upgrade cost?

I'm still not sure what I'm going to do yet. I want the avengers but would rather have just black widow and captain america. I wouldn't use Iron man or thor that much. And I'm trying to clamp down on figures. Last year I got Davy Jones, barbossa, mike,lone ranger and tonto and I never use them. I'd rather get black widow captain America and a disney toy box and be happy. But I'm also upgrading to ps4 so its not ideal.
