Not until next year, when the exclusivity agreement with DISH expires. Eventually, I do think it will happen because Gol TV has mentioned the possibility of broadcasting in HDTV in the next few years.
I've heard that Voom's WorldSport HD channel and Gol TV have partnered in broadcasting La Liga and UEFA Cup games this past season in HD. I would guess that you will see Gol TV wind up on Voom, when Gol TV goes HD fulltime. If that happens, its any one's guess what Voom decides to do with WorldSport. Maybe W.S. will show other soccer matches that are not on Gol TV. This is all of course pure speculation.
