Saw this posted on the dealer inventory management website:
This is the LAST month for MY12 Ordering for all vehicles except Passat and Routan. Next month will be the first MY13 orders for most carlines.
I just got off the phone with someone at VW distribution support and he confirmed to me, after checking with the actual head of logistics and distribution, that any sold order placed by tomorrow will be a MY12 R but after that they will be MY13 and that there is currently no planned end of production for the R.
He also told me that there are no planned changes to the MY13 R from the 12, other than the model year designation.
