I'm in the same boat as you. I really don't need 32GB... I have like 3 gigs of music. I was going to get the 16GB 3G with the camera if it was $199 or $229 and I assumed they would discontinue the 8GB.
Get a 16GB 2G? Best Buy has them for $220+tax.
I thought about getting that, but the rumor mill keeps making me want to wait for a possible camera in early 2010. The rumors seem to indicate the camera will only go to the 32/64.
If you think a camera is important, you will have to wait, and shell out extra for memory you don't need.
If you don't think a camera is important, I say buy now.
