have you thought about custom bedding? we did ours through new arrivals, but for a girl. We're reusing it for this baby too. There are others: javis davis, layla grace, posh tots. try googling.
I convinced DH to agree to a classic winnie the pooh theme. I am all about children's lit and it seems like a pretty gender neutral theme. If it seems a little girly, consider that Pooh's BFF is a boy and that the colors aren't really pink or blue.
Re: We can't find any boy bedding we agree on
If you want something neutral check out. It's what we like because we aren't finding out either. pricy, but cute!

i don't like a majority of the boy bedding out there. It's no where near as fun/interesting as girl stuff.
Have you seen Nurseryworks bedding? they have some really cute/modern/gender neutral sets.
OOOHHH! This is adorable! I love the bedding!
We are going with this one. DH loved it and of course I did. I like the light colors.
