WHEN? Sony When?

Why is Sony, the creator of the walkman, the Cd and the playstation, takin soo long to announce when the PS3 is goin o come out, what is it with this guys?, just come up with a date and well be happy.
The PS3 is capable of all those rumors online? YES but i might not be availaible right out of the box. who cares as long as i have the box in my house. i really dont care if it cost $500 anymore, i mean its goin t be able to do almost anything what a computer can do. Lets just kill XBOX asap.
