It seems like they've had sales to clear out old inventory (as Parametrek said), since some of the recent sales have included a significant number of their XML2 models and models without magnetic charging. There has also been discussion of a limited run Nichia 144A version of the Wizard Pro, so it wouldn't surprise me to see a few other high CRI models or other updates. Following what iamlucky13 said, the sales might also be to generate interest so they can capitalize on whatever new models they plan to release.
