This is great news and I am excited for it, but honestly, this along with Nintendo's previous announcement they're bringing GBA support to Wii U's VC and not 3DS' baffles me (which we're still waiting for). Both portables should be released for both VC services, and I feel they should bring them to 3DS' VC service first if they are not going to release them for both at the same time.
There's still a lot more Nintendo could be doing to improve Virtual Console however. A great start would be to add a unified game purchase system (so we're not having to buy the same game multiple times just so we can play it on our 3DS and our Wii U), considerably increase how many VC games are released per week, and add all the classic systems Wii's VC service supported that Wii U's is currently missing.
We know N64 support is coming to Wii U's VC, but they need to make sure the N64's Controller, Rumble, and Expansion Pak accessories are all properly emulated this time. The Rumble Pak should be easy, and the Expansion Pak was already supported on Wii's VC. So there's no excuse why they can't do it for Wii U's. The biggest concern is if Nintendo doesn't emulate the N64 Controller Pak again. That would effectively negate the possibility of some of the N64's best games from coming to Wii U's VC service because you wouldn't be able to save your progress. And that's bull****. Not to mention there were quite a few N64 games that didn't require it to save your progress, but used it for other neat gameplay purposes. Mario Kart 64's Time Trial Ghost save feature is a good example.
I also think it would be in Nintendo's best interest to add support for GB, GBC, Game Gear, Dreamcast, Sega CD/32x, and Saturn to Wii U's VC, and on top of the GBA & DS support mentioned above, add support for Virtual Boy, SNES, N64, TG-16, Arcade, MSX, C64, Neo Geo, Master System, Mega Drive, and all the Wonder Swan & Neo Geo Pocket series to 3DS' VC.

Chance favors the prepared mind.
