Rumors creeping in of streaming video support for new BlackBerrys could be validated if comments from Slingbox’s CEO turn out to be true. In a recent interview on Revision3’s show GigaOM, Blake Krikorian suggested that a mobile client for Sling could be coming to BlackBerry. Considering Slingplayer Mobile is already available for Windows Mobile and Palm devices, BlackBerry-compatible software isn’t much of a surprise. User-friendliness aside, would a service like this match the entertainment value available from iPhone video streaming? Of course, comparable products such as Mobile TV Center are already out on the market, and offer extra features such as show recording, but with the slew of new Slingbox services detailed in the interview, it’ll be a tough fight.
