There is a very specific reason that the FR-S Convertible as well as other hardware-intensive, beyond-accessories, modified versions from being approved for production. For one, there is a big reason of this... Subaru is making XV and Forester on the same production line at the same plant, and the two cars have just debuted and is a a huge demand as one of the most successful Subaru cars in this decade. So there isn't a huge capacity to make more FR-S/86/BRZ that's already on backorder for almost every nation and region outside the USA.
There are other reasons but this is one of the biggest delays as of now.
And no, the project has not been canned or shelved, but is pretty much alive, and Toyota is simply looking for a solution and some time, so that more drastic methods don't have to be taken to make it significantly more expensive or complicated. Remember, that the President of Toyota Motor Company, is very fond of this car and that things will not go down without a big enough reason, and this is not a big enough reason.
