You won't necessarily have to wait for months to get your hands on the next-gen PS5 headset either, as The Verge points out. As things stand, Sony expects to deliver the device between its February 22nd launch date and February 28th.
The initial wave of pre-orders required would-be PS VR2 owners to register their interest and hope they got an invitation from Sony. Now, you can reserve one and at least give yourself the option picking up the headset in February, especially given that it's unclear how much stock Sony will have at launch. You could always cancel a pre-order if you change your mind.
You'll have to dig deep into your pocket to actually buy a PS VR2. The headset costs $550 and you'll need a PS5 to actually use the thing. Games from the original PS VR aren't compatible with the latest model either, so you'll need to build a fresh library of games or hope developers offer free PS VR2 upgrades. Polyarc just confirmed that it's bringing Moss and Moss: Book II to PS VR2, while Sony's positioning Guerrilla Games' Horizon Call of the Mountain, a Horizon Zero Dawn and Forbidden West VR spin-off, as the flagship launch title.
