This is really a shame. I bought it, and it's a great version of the game. I just finished playing some Double Weapon XP Weekend. Personally, I'm done with CoD and FPS games in general after pointer controls are abandoned, but I know I'm a tiny minority.
I don't think you can blame Activision or even the person that said this. They greenlit the game, had it ready for launch, and gave it unique features, even supporting the legacy Wiimote controls that the community liked from Wii. Treyarch has kept the CoD community going with patches, and they had been pushing user names and modern friend requests even when Nintendo was stuck in the friend code zone.
It was Nintendo that launched their console a week after Blops 2. Nintendo were the ones that didn't let Activision advertise early or even talk about the game. It's the biggest third-party game going, but Nintendo's attitude has been that if people buy the console, then the Wii U is entitled to get third party support.
Well, not enough people bought the console. And if they did, the biggest game Nintendo pushed was another minigame collection. Nintendo made it very difficult to build an online community due to years of friend codes and an underpowered console. They're just reaping what they've sown.
As for DLC, Activision can't even release the DLC because it'd split the already tiny userbase in two.
I hope Activision continues support because I love CoD with pointer controls, but I worry about the future. I feel bad for Treyarch who did a great job with the game.
