Wild is nice, yea, but I think most agree it won't be their primary home. I will definitely try to break the game with a full collection in Wild. I have hopes of an even more complete Rogue Mill deck someday being possible, which wont ever be possible in Standard.
The saddest thing for me will never being able to play Combo Druid / Handlock / Freeze Mage / etc if they actually make big nerfs to the classic cards. Everyone expects Force/Savage to be nerfed, which is definitely needed, but sucks it'll be a deck we can't even play in Wild. Watching Kibler's video and the latest Value Town, the "pro" dudes bring up a lot of other cards that probably should get nerfed too... like Molten/Mountain giants. If those aren't nerfed then BGH needs stick around to counter, and also Handlock remains a viable deck forever which in a world where we're trying to change the meta periodically, you don't always want Handlock around, or freeze mage, etc.
