I agree it's just Sprint being Sprint. Also it may have to do with just keeping supply and demand. If they announce it too early that could lead to less units preordered. I would think by keeping the mystery around it pushes more people to go out and preorder the phone "just in case". Just speculation though I'm sure it's probably something much more simpler than that.
I was on the fence ordering online via Sprint or walking into BB to pre order. The only reason I went the BB route was because, I herd no word of a early release going through Sprints site, like they did with 3VO. I'll put in a prayer for you folks that went through Sprint online getting it on the 15th or earlier 
I liked being able to easily visualize the quality of connectivity I had via 4G. It had the 3 signal bars above the 4G.
