Immersed and PFD are smaller companies releasing their first hardware; yes they've missed their initial estimated ship dates but they have actual working prototypes that have been tried by users (e.g. PFD had a booth at CES). The only question is if they can ramp up manufacturing. I expect them to have shipped their preorders by March and then we'll find out if they can scale.
HOWEVER my timeline suggests that you wait until the end of the year. The 4K per eye panel is now a commodity [1] and I expect a lot of VR glasses to show up in the next few months. Don't be tempted by the first few unless you have the budget for the cutting edge. Immersed is pushing their subscription software and requires a companion app on the host device. PFD is offering an Android Vision Pro clone. There are a couple PCVR (gaming) headsets coming. For coding though, the ideal is probably a simple headset with plug-and-play video input (i.e. like a high-res Slamglass [2] or GOOVIS art [3]). It's worth waiting in my opinion to see if anyone uses the panel for that.
