iPad Album Artwork?

I just got my new iPad... Loving it. I can't believe how many of the apps are already retinized! Nothing like the horrible wait with the iPhone 4.

Anyway, I spent a lot of time hunting for 1000x1000 artwork for my 30GB of music - it looked great on my iPhone and my old iPad. Now that my new iPad has a huge retina display, my artwork will look crappy once more. Does iTunes have higher resolution artwork? Or should I just restore from iCloud? Thanks.
