I think that if Sony were really serious about selling the HDD in mass quantities, they should consider releasing a 5GB hdd for 25 bux or less (More than enough room for a DVD to stream data onto + other features), a 10GB hdd for 40 bux or less, a 20GB for 60 bux or less, and... well you get the idea. That way the consumer can temper his desire for online content with a variety of different size and price options.
Starting June or Nov of next year, Sony should also begin including an at LEAST 2GB upgradable HDD INTO the PS2 so that future consumers aren\'t forced to buy expensive and bulky addon\'s. (Not to mention that\'s all the more oppertunity for game devs to make suped up HDD REQUIRED games)
