Looking good !
I have the 2010 Laluz and the 2010 Prizma, and I wonder how can they be any better?
Guess I'll wait the demo to find out
If yours are not falling apart then probably no need. Really boards just don't change all that much from year to year or a few for that matter.
Well... Xenon's first batch of boards were produced in 2009.
They do make small changes from year to year especially in the footstraps and pads.
I guess you are right, there is no real need to replace a board that you like.
If I recall the warranty on the 2009 and 2010 Xenon boards was for 3 years, so again no need to replace it.
