I'm optimistic about this. There is tons of smoke around the rumor that Disney wants to introduce a one-stop-shop streaming service for sports. It has been reported that the major goal of this acquisition was to obtain regional broadcast rights for hockey and baseball and this makes Disney the majority owner of BAM (the company who runs NHL.TV and MLB.TV). ANyone who complains about blackouts through NHL.TV should be cautiously optimistic about this. A company is interested in offering a major sports streaming service and now owns over half the regional contracts that are the source of blackouts.
Now, it remains to be seen what the final product looks like, but there is a possibility that Disney/ESPN will begin to offer the paid streaming service that people have been asking for. Even if blackouts still exist, I'd rather purchase one service from ESPN for Cardinals, Blues, college football and some NFL than pay for 3 separate streaming services.
