This is not really a news blog, but I spotted something on a recent video titled "Reuters visits the Raspberry Pi factory" at raspberrypi.org.
The picture below is a screenshot from about 2 minutes 17 seconds into the video. It shows a box labelled RASPBERRY PI 4GB U-ICC-005-43 and a photo of a board.

The picture is a bit blurry, but the board appears to show some differences from the three boards I have. I don't think it's a model B1, B2 or A. So what is it?
I've not heard any plans to release a new model with a lot more memory, but given that the increase from 256MB to 512MB was essentially free to end users, it certainly seems a possibility.
Or maybe everyone has already discussed this and I just missed it.
