Longevity is only questioned because of fairly new tech. A twin turbo designed for heavier duty use instead of speed is new tech. The reliabilty of an engine constantly being fed boost seems like greater chances for things to fail vs. a traditional V8 which loafs along.
This is just my speculation though. I have no data to back it up, just me being skeptical. Diesels have proven that a turbo'd engine can last, but the characteristics between the two engines are quite different. I think the EB can be reliable as a heavier duty engine, but I wouldn't want to put my money there until these things have more data points (only in terms of longevity, I don't think the fuel economy will ever be there).
