RIM has already said that PlayBook OS 2.0 will be available in February. But according to a leaked roadmap obtained by n4bb, that’s just the tip of the iceberg.
N4bb also reports that RIM will launch an updated 7 inch PlayBook in April with 3G+ support. Then in December we could see a 10 inch PlayBook with support for 4G LTE.
The roadmap also shows the first smartphone running BlackBerry 10 software in September, new phones for emerging markets, and a summer launch for a service that will allow IT administrators to manage the PlayBook.
Right now this is little more than unsubstantiated rumor, but n4bb’s sources are usually pretty reliable.
