My 08 one has the spots to cut out as well. I want to use the OEM look switches, which you can still see the hole with so i thought the 2012 one would look neater. If i was using Carling that covers the hole better I probably would have just cut them out...
You can see the colour difference to the old blank plugs, but once filled with switches it wont be as noticeable.
The part number for the little square piece that fills the AUX/USB hole is: 555390D090B2
