Coming to HTC Vive and Valve Index.

In March 2019, Valve surprised the VR industry with the tease of ‘Index’, its first self-made VR headset. Index would go on to launch later in May 2019 and be seen as the enthusiasts’ choice in PC VR headsets for many years to come. Unbeknownst to the world, by the time Index was released, the company had already been working on aspects of what would become its second VR headset, Steam Frame.

Viveport, the VR retail platform from HTC is now giving developers 90% of their game revenue, instead of a 70/30 spilt like Steam.
It could be free and it wouldn't matter at this point. There isn't really a PCVR Market and I say that as a PCVR user. It is modders and enthusiasts with a few retail products on Steam.

Valve reassuringly states: "We're Still Working on VR" in a recent interview, whilst confirming the Steam Deck and VR teams work together.
I wonder if that means some games will be VR only again.
I just want them to go back to their roots where the majority of their games are made for a modern mid/high spec PC.
They are talking about hardware here and the direction that Valve might take with future hardware. And, interestingly, they might be going the standalone route. This is honestly the way to go if they want the device to reach more people as shown by the Quest 2 sales.
