Really, I don't have sympathy for people who drop money on new hardware for the promise of exclusives. The video game world is never absolute, stuff always gets delayed or cancelled or changed. I mean, the Wii U with the library it currently has is pretty weak. People should have based their decision to buy it on the games it has, not the games it potentially will have.
Take the Dreamcast as an example. Sure it had a lot of titles releasing down the line, but the initial 9-9-99 launch lineup was awesome and totally warranted a purchase. Dreamcast fans were screwed over with the occasional promised titles that were canned or lost exclusivity to the PS2, but there was still so many great games early on in the console's lifespan that it warranted a launch purchase.
Wii U, meanwhile, seems to rely more on promises than what it is actually delivering. Someday it'll have great exclusive titles, but that day has yet to come and I really don't feel sorry for people who had the money to spend on the console at launch. If anything, I have sympathy for the people waiting for the good games so they can pull the trigger and buy it. Unless Nintendo has the next big Zelda and/or Mario game planned for late 2013, Wii U is still not an appealing console.
Hell, I see Wii U owners talking about upcoming games and Lego City Undercover seems to be to only game they really have a firm impending release date for. That's not exciting!
