Although not mentioned as part of today's Xbox 360 price drop announcement, more evidence is coming in that the Xbox 360 Core model may be finished. An employee of a Target store took multiple images (sadly the clearest one is above) of the store's PDA showing the Core model as "discontinued" in the "status" bar at the top right.
This follows last week's Best Buy information that the Core model was finished there as well. The stories are starting to stack up. We've been told by numerous sources that their various stores haven't stocked Core units in a while, this all feels identical to the way the PS3 20GB death occurred earlier this year.
