The results and analysis for Blu-ray (and DVD) sales for the week ending 5th February 2011 has just been posted. Red was still the week's top selling Blu-ray title, which indicates a fairly slow week in terms of new releases, although Disney's Blu-ray+DVD combo 60th Anniversary edition of Alice in Wonderland did do very well, and there does not seem to be a DVD-only version of the movie on the horizon (at least none listed on Amazon for sale).
And so the lack of hit new releases meant that Blu-ray market share fell a little from recent highs, although there were still 3 new releases in the Blu-ray top 10.
