What are you afraid of?
We all know what Lucas is afraid of, that the OT would easily outsell the crappy SSE 2004 edition, and he'd have to weather the ridicule and embarassment of the general public slamming not only his crappy prequels, but his terrible updates of the classic OT. That's why Lucas would never release the OT, because he wants the terrible SSE 2004 edition to win by default.
But what do the fanboys have to fear? Why are they so against the OT?
