Larger budgets for Gainax productions and less pointless fanservice shit? Win.
Note: Disney still has a 2d studio open and is working on a 2d feature right now; it's not just CG animals jumping around and making cultural references.
But yeah I'd love to see stuff like Gurren and Diebuster with epic western budgets. Even Gonzo's bullshit looked surprisingly decent when given more animation funds (Afro Samurai lawl), just imagine someone like Hiroyuki Imaishi working like that.
