I want to just point this out for reference..
Transformers in Hollywood started construction in September 2009 and as people know, it opened May 2012. Then in the case of Orlandos counterpart, that same attraction opened up about ten months after the walls came up for the clone in Late May/Early June of 2012-2013 for soundstage 44 (If I'm wrong there, correct me as I'd love to know).
Taking that into perspective, Fast and Furious started construction by demolishing the Mummy tunnel at Hollywood in September of 2013 and opened in June of this year. Doesn't that seem a little too off for a project that's supposedly a clone if its aimed to open for Late 2017? And I get it, it might be due to the larger demolishment of the left side of San Fran but you got a lot of construction time if your aiming for Late 2017.
Transformers:
Hollywood - 32 Months from Backdraft closing to the Ride Opening.
Orlando - 12/13 Months from Stage 44 Demolishment to Ride Opening.
Fast and Furious:
Hollywood - 22 Months from Mummy Tunnel closure to Opening of Animation.
(Estimated if its still Late 2017) Orlando - 25/27 Months from Disaster closure to Ride Opening.
(These are all estimated and I looked from StudioTour, and other places)
