Given the way economics works in hard drives, I wouldn't be surprised if the 80G part was actually cheaper than the 60, these days. The volume is driven by capacity, and the sweet spot seems to be around 100G. That would make demand for 60G parts significantly down compared to 80G parts. Given therefore that more factories will be making 80G drives, I would expect them to actually come in cheaper than the 60G ones. The differential is not enough for industrial customers to be pushing demand for 60G parts in the way they do for the much smaller 20G parts.

80G more expensive than 60? I doubt it
