No date is rumored yet:
EDIT: this could be the upcoming (160 GB) model:
http://arstechnica.com/journals/thumbs.ars/2008/01/27/mole-80gb-ps3-dead-120-160gb-with-dual-shock-3-incomingOur inside source of all things video gaming has been right almost every time it comes out of the shadows to give us information, so I'm going to dispense with the back story. Wherever his or her information is coming from, it's usually solid. After I spoke to Sony about the possible discontinuation of the 80GB PS3 model, I lit the mole-signal.
Working late into the night on Saturday, I heard a noise behind me. For both of our safety, I didn't turn around. "You've talked to Sony," the mole said in a gravelly whisper. "Tell me what they told you."
I repeated the information we reported on Friday: Sony is sticking to a two-model approach at retail, but the company won't comment on whether or not the other model would be the 80GB system. The 40GB system seems safe. I asked the mole what information he had.
"Sony is, in fact, phasing out the 80GB PS3. Sony is going to stay with the two-SKU approach though, and the prices look to stay the same," the mole told me. I heard sirens in the background, and the mole seemed nervous. "The Spiderman 3 pack-in will disappear as well once the 80GB unit is gone. In order to maintain a similar value proposition to the 80GB/Spiderman 3 bundle, I expect to see a storage increase to 120 or 160GB at the same price point, plus the new Dual-Shock 3 controller... what are you trying to accomplish with this story?"
