Many of the websites seem to still have pics of the older version. I think that the pipline has been filled with the newer versions for quite some time now. I would be very surprised if you got the older version in any online order these days.
In fact, if you happened to get an older one you could easily sell it for what you paid for it (or more) on CPF/MP. The older ones with their two-piece heads are lego-able with the Fenix LD01 & older Preon heads - the newer ones have an integrated front end and cannot easily be upgraded.
I wouldn't worry about it either way.
