What i've read on cycling news suggests that they used rims branded as "PROtotype" last year and are now branded shimano. I figured that meant that they were developed by pro/shimano rather than hed. Maybe your right though and they are all just rebadged hed rims
Those "PROtotype" ones were using HED Stinger rims built onto Dura-Ace hubs.
