Well, I guess I'm not buying Wind Waker HD then. Nintendo hasn't justified that $50 price point with as little as they are adding to that game, as well as how minimal the HD upgrade appears. Meanwhile, I can buy Kingdom Hearts 1.5 and Final Fantasies X/X-2 HD this Fall, both containing 2 games for $10 less than Wind Waker HD and both containing substantial new content (and in FF X's case, the HD upgrade is far more impressive).
If Nintendo were adding the missing dungeons (yes, I know those ended up in Twilight Princess. They could design new dungeons); gut the Triforce quest; and take all the stupid tedium out of sailing, that would be worth the $15. Instead, they put Miiverse in a bottle, added some minor tweaks to sailing, and dumped bloom lighting on the game. That's just not worth $50 for me, only $10 less then the price of a new game and $10-$20 more than better HD collections.
