I know they're coming soon, but is there any reports/rumors or indications as to how much external hard drives with Thunderbolt connectivity will cost? Currently, 2TB ext HD can be bought as low as $80-100. That's quite a deal, and I will need one soon to Time Machine my MBP (I'm running it without any backup currently). I'm hoping to wait for Thunderbolt connectivity, but if TB connectivity will jack the price up considerably, then I will not wait for it since I'm not willing to spend too much on an ext HD just to have faster transfers. Any insight? PS. I'm also planning to purchase an iMac after its refresh, which is why I want a 2TB ext. HD. I plan to Time Machine that too with the same ext HD.
