Russ,
As you mentioned, I also saw the recent "update" regarding the Desert Storm version of the RFM Sheridan. And like most, it's become a case of "believing when I'm seeing it". I am also in the holding pattern regarding the Nike Hercules missile that was announced either in 2018 o 2017. And yes, I'll "bump" the thread in order to maybe, just possibly, gain the attention of someone with more recent knowledge of the subject. Almost universally, there will be a response from somewhere in the world from a person with that bit of information that can inspire me to keep waiting or to move along. We all have a similar experience for one release or another.
Asking for input from Armorama members should bring constructive responses. Anyone with access to the internet has by this time already decided whether to utilize FB or not; lots of opportunity for good as well as not-so-good stuff from there. I don't judge anyone by whether they use it or not. After all, we use this site as our means of communicating with like-minded modelers, right? And it's not FB, although sometimes members may treat it as such.
As for the Facebook pages from the manufacturer, yes, I visit once in a while for news on the Sheridans, but frequently it seems that there will be no updates at all, other than yet another Tiger, Panther, Berge, etc release that apparently has a higher release value than the Sheridan which has been in the wings for years. And yes, this will continue to happen, so while I wait, I finish something else in the "pending" pile of kits in my stash. It'll happen, hang in there!
