Yep, good eye Richard - almost all HL publicity photos depict pre-release versions of the models. Typically the most obvious difference is the lack of a railing around the lens room. Take a look at the 'Preview of '99 Introductions' on the HL-dot-com site to see other photos of 'beta' models. Or check a Lighthouse Depot catalog to see earlier years. HL has been using photos of pre-release models for as long as I can remember.
