I went on Boattrader.com and looked at about 20 new 2013 X30's, and some (2 or 3) actually had the same trailer that you have, though the majority had the newer look. Most had the polished cans as well but a few did have the black ones.
It would be worth asking your dealer about it. I ordered my 2013 in September, got it in February, and I would have lost my mind if the trailer wasnt the new one or the cans were black. Does your X30 have the Pro Package?
Anyone shed any light on this?
