Perhaps DVC does not have alot of choice in the timing. It has been well documented on the boards that the North Wing is in pretty bad shape. If a decision has indeed been made then the timelines maybe shorter then we think.
Here are the options that I think Disney has regarding the North Wing, if indeed the plan is to hand them over to DVC.
1) Invest millions into the facility to bring it back up to standard, then hand over to DVC in about 4 - 5 years for it to be demolished and re-bulit.
2) Allow it to continue to deteriorate for 4 - 5 years, then hand over to DVC.
3) Close it sooner, board the windows and allow it to sit. DVC will then take it over when ready (SSR is sold-out and EP is open and 25% sold out).
4) Realize that it is in a high-profile location and that something needs to be done sooner then later. This resulting in the rumor reported on Screamscape this morning.
My conclusion - If the plan is to convert CR's North Wing to DVC, then number 4. If the plan is not to convert to DVC then we should see an announcement soon (6 - 12 months) regarding a major re-furb.
Then again, as I have said before, nothing would suprise me.
