The current models are based on the 2008 with the integrated tail. There are varying versions of this boat though with various volume. However, I think what is called the L cutdown, is essentially the 2008 cutdown (which i think became the standard. The non cutdown had huge nose volume).
The 2010 is quite different. It was very flat through the knees compared to the 08 and the new.
If you want more information, talk to Cam Butler at Polo Mania. He will be able to give you all the details of the current range of boats and how they are different (or not) from the 08.
