Should I wait for the iPod Classic 7th Generation to be released to buy an iPod?

I currently have a 2nd Generation iPod Nano with 4GB. I ran out of space and I need to buy a new iPod. When do you think the new iPod classic will be released? Is it worth the wait, or should I just buy a 6th Generation?
Also, I’m planning to buy this in a few months when I will have extra money. My friend said that perhaps the 7th generation will come out sooner because of problems with the 6th.
