Honestly I really like the 3D for games that do well--and it honestly depends on the game because some games are lazy with it and put no effort but if you want to see GOOD usage of the 3D effect, look at the StreetPass panels in 3D, those are BEAUTIFUL (IMO of course) and some of them actually pop-out/look like you can touch them which is awesome. That being said, the fact that 3D is limited to battles isn't that disappointing--there won't be much awesomeness to the 3D effect in other places, but battles will benefit the most from it IMO. That's not to say I'm a bit disappointed they aren't doing more, but it's nothing to raise hell about either, IMO, especially given the fact that many people don't enjoy the 3D/see it as a gimmick (which it kinda is even though I like it myself)/get a headache from it (I do if I use it too long) etc.
