I'm really looking forward to Pearl Jam's "Ten" and SRV's "Texas Flood" So far looking at end of march for Ten and as far as I know, they haven't annouced a date for Texas Flood yet.
I haven't seen a date for Texas Flood, either. But If you preorder the new special edition anniversary release of "Ten" at Best Buy, you'll apparently get three extra Rock Band tracks for PS3 or XBox360: "Brother", "Alive" (Live from the Drop in the Park concert) and "State of Love and Trust" (Live from the Drop in the Park concert).
Also, the rest of "Chinese Democracy" is on its way, as well. But that's about as exciting as waiting for the light in traffic.
