Mysterious pictures appear on Vietnamese website.
While the world waits for Apple to announce a seven inch iPad, here comes an entirely unexpected addition to the rumour mill: are RIM working on a ten inch BlackBerry Playbook?
These pictures are from Vietmanese site Tinhte and appears to show a big brother to BlackBerry's underwhelming seven-incher released last year.
The tablet appears to have an iPad-esque 4:3 aspect ratio, 10-inch display and a SIM card slot, presumably for 4G.
In terms of design, the new tablet mirrors the smaller, original tablet, with a glass front and rubberised back.
According to a leaked roadmap, a larger tablet codenamed Blackforest is due next year.
