Very close, 2 weeks to be exact.
I'd like it if they did, and who knows, they may, but I don't think they'll follow the Pandora model. While TSL is a big deal, it's no Pandora. Below is the Pandora pre-opening schedule for reference.

WDW CM preview lottery, 5/5 through 5/12. (and "no", I didn't win)

Press, 5/23 & 5/25
