Damnit, so many awesome shmup things. I'll have to start saving up. But yeah, I'd want just the box for now. And if the boxes themselves are really random... I'd get a double set. I'm also looking for Lucky Star figures... </shameless plug>
If you want, you can also preorder then from NCSX.
They are initially selling them in complete sets, 1 of each of the 5, which ship in early December. The boxes of 12 they are selling later are random, but also include alternate color schemes for most of the ships.
