I grabbed then when I saw it was available last night. So far I'm rather disappointed. It looked like it was going to be a simple game, but I had a lot of trouble finding the clouds, and it took me a while to go through what would have been a quick tutorial. I don't know what I'm doing wrong. (I know the clouds take a while to come back once you've found them.)
There's a review up-

I don't have such plans yet since I've barely played B/W and want to finish that first, but I thought it'd be a fun diversion until I got through it, and then I'd already have the Pokemon caught to transfer later. But honestly so far its not that fun.
You can only catch a handful of Pokemon in it (in addition to finding items), and you don't do anything else with what you've caught other than transfer it to B/W 2. The only other cool thing is if you have a 4th gen game in your slot, you can find like 5 of those legendaries- Lugia, etc. So that can be good if you wanted those but weren't able to get them otherwise.
