Hi @Canieatunow, welcome to exciting and fast paced world of VR. The Vive HMD hardware revisions that are lighter have been shipping for quite some time now so if you purchase the Vive through us or any major retailer that sees high stock turnover you'll definitely receive the lighter version. The lighthouses have seen slight revisions as well. If you're referring to lighthouses with the recently announced Steamtracking 2.0, those won't be available for quite some time.
To reach Viveport's customer service team, email firstname.lastname@example.org
