I also believe in this. Every update is always the same story, they announce something long ago but only really start developing (and thinking) on the eve of the release. And worse, after they launch, they take forever to make corrections or never do them, focusing on new updates.
Actually, they tend to make really cool and fun lore consistent things, but then people who want to retcon the game lore out of existence so they can play a WW2 flight simulator come along and whine about how they don't like something and then they complain until the Devs have to redesign things and delay releases by months.
The 3PV camera is the most lore consistent solution, given that the technology exists in universe for spaceships to perfectly track objects in space around them (and simulate noises they make), and that a staple of the setting is that realer-than-life virtual reality is a thing. The 3PV camera is literally just a marriage of two already existing technologies, the simulated reality expert system (Arena, Navigational Computer), and the tracking sensors (sound simulation), which, combined, project a perfectly realistic third person view for your gunner to use.
It's entirely lore consistent, and it's also very fun and cool. The demo showed that it has obviously been given a lot of attention and is very consistent with the lore, they've clearly been working on this for a long time. If there are delays, it will be because a lot of people who for whatever reason do not like or understand the Elite series of games want to retcon it into some kind of spaceships-are-submarines-and-it's-1937 style game.
It's okay that you don't understand the Elite canon, because there's a lot of it and a lot of it has been explained through multiple generations of games as easter eggs or in descriptions and so on, but all of the technologies people are complaining about in this update are 100% consistent with the lore of these games.
