We've seen screenshots, and we've even seen it in action, but now Sharon R., in her first corporate blog post for Sling Media, has laid down the law by announcing a Tuesday, October 31st release date (yea, All Hallows' Eve) of their much-anticipated SlingPlayer for Mac OS X public beta. She even went so far as to 'guarantee' it, so that's gotta be worth something. We'll see whether they get hung up by a little too much partying over the weekend soon enough. Stay tuned (hah!).
