Campagnolo Veloce vs Centaur vs Shimano 105

Are all the groupsets as durable as each other? I'm planning on having a new steel frame built up and attaching a groupset to it so I would like to make sure the bike lasts. When exactly will the new SRAM products come out?

AFAIK they're all pretty durable.

For a nice steel frame, I'd go with some alu Athena. Looks, cormfort, and funtionality (IMHO).
