Seagate vs. Hitachi: Prediction for 2009

Following last week announcement from Hitachi and its expectation of 3.5" HD with 2TB storage space, Seagate fired back today by releasing its prediction for 2009: 2.5TB on a 3.5"HD.
So according to those 2 manufacturers, 2009 should be the HD's year...
Despite big announcements only released for marketing reasons, it would also be important for customers to have HDs available in shops... after CPUs and GPUs, HDs are currently also affected by the ghost syndrome: officially available, but in reality not on the shelves.
