Maybe I am just being a party pooper but considering the Tupac hologram is closely linked with Dre and everything Dre does is a huge money whoring exercise, I just am not that impressed. Sure its a cool novelty but besides the initial $ it cost to program, now Dre just has a free tool to tour around with and make $ off of. Ive seen a few youtube videos labeled "Dre speaks out about Tupac touring" etc... and I havent been bothered to watch them. Sorry if I am misinformed, but as of now this whole hologram business seems incredibly overhyped.
On a side note, apparently there were supposed to be a lot more hologram performances during Snoop and Dre's performance but they were having a lot of technical difficulties weekend 1. Weird that they didn't have those kinks worked out by weekend 2.
