Well I'm thinking of getting a new iPod Classic soon so now is the time I check out any rumours of new iPods to see if I should hang on a bit.
Good point about 160Gb being max possible capacity. No way will Apple bundle two back to back, the iPod is known for being slim so this won't happen.
They could use SSD but seeing as 64Gb ones etc cost £500+ that won't happen for ages unless Apple can get a brilliant deal.
