I don't think the GO2A is on general release yet:
1. I think LHLabs are providing an opportunity to upgrade first, for their GOV2 backers. They would be absolutely panned if they didn't.
2. An upgrade 'manufacturing process' is quite different from a product delivery. In some senses it's more difficult (eg the communication and returns activity), in another way, it's easier, as the components being upgraded are quite few, and I'd guess, discrete.
3. Ultimately the LHLabs Geek Out line will survive if it gets good ratings from reviewers AND customers. For that to happen, it needs to have transitioned off the 3D-printed chassis. I'm not saying 3D-printing is a complete mistake - it just doesn't, currently, have the look, feel or structural integrity required.
4. Once the V2+ backlog has been delivered and the GO2A upgrade completed, I'm sure we'll see general release.
I'd also suggest LHLabs look at their product naming conventions: it's too easy to get the wrong product, currently, when doing Google searches.
