I don't see them recouping the R&D costs on these iterations, any profit they're making on manufacturing these devices is being reinvested, they're each developing a brand/platform which they can lean on in the future to target a more mainstream audience with cheaper devices not reliant on external hardware.
To gauge success you have to look 3-5 years down the line and see whether software/services are still being developed with VR in mind. Then further down the line, whether iterations are being made with the mainstream in mind.
That being said, sales aren't unimportant to success, otherwise what incentive is their for developers. 5-10m sounds good for developers, people who have invested in these devices have more incentive to purchase software at higher than normal attach rates so I don't think they need to be selling in the 10s of millions to be successful in that regard, then it's just down to the quality of the software itself.
Don't ruin the moment
