All three of those were acquisitions, which seems to sorta prove the point.

The Quest 2 was not an acquisition. Oculus was an acquisition. Then, over 6 years later, the Quest 2 was released. Not sure anyone can claim that FB didn't have a huge role in inventing the Quest 2 after 6 years of building up to it.

I’ve got both Quests. The 2 is nice, but it’s not very different from the first gen; upped specs and resolution. The first gen was nice; separating it from the PC was important, but it’s still hard to see it as that innovative over the Rift predecessor it largely inherited from.
