Didn't expect this at all. I think a lot of people with fond memories will get a shock at how basic and grindy the game was at launch. It would seem like such a basic and empty MMO experience these days and be lacking tons of features. In my opinion, obviously.
I'm predicting a lot of UI issues with this thing. There's a lot of games that switch the UI automatically when you use your controller and switch back to keyboard mode when you use your keyboard again. So.. based on the info we have, this new keyboard will make games with that feature switch the UI constantly because it will think you keep changing input type.
Rifts were the worst thing to happen to D3 imo. It turned it into a roguelike time trial endgame. The classic random map drops done by other aRPGs is the better method. Blizzard tried something different, that's cool, but it's not for me. Especially the set piece dungeons.. my god.. nothing like giving you ridiculous amounts of skills and loot and then forcing you play a certain way. Hate it. WoW isn't going to benefit from that type of game play, it changes the essence of what these games are supposed to be.
