Wow, they're really milking that House of Blues thing. As a performance, it wasn't anything special by 2pac or the Outlaws. It has its bits but.........The Snoop Dogg and Dogg Pound performance give the whole thing a lot more life. The music catalog on blu ray isn't that massive anyway so I guess they may as well add this one to it.
In terms of anything else blu ray, I don't know if they have plans. I've not even seen a hint of publicity on the web. I'd say
Tupac: Resurrection is a good candidate for a blu ray release.
Juice would be a close second. Actually, the amount of blu ray releases isn't as large as one may expect as of now. You'd probably be worried if blu ray releases were as many as current DVD releases and, nothing 2pac related was out. It may be a while but, one will be out eventually..........I mean come on,
Chicken Little is out on blu ray

This is a good site for plenty of blu ray info
Blu-ray Disc US Site
Does the trend on blu ray releases lean heavily towards Sony/Columbia more than other studios or companies??
