If anyone missed these and don't mind paying a tenner more (still cheaper than anywhere) they have them at simply games for £79.95. Not putting that deal up as these are 69.99 and that basically RRP so 79.95 is even worse even though it's still the cheapest around. Better than £120 though so if you really need them they're here.
Given that Sony can't even support PS4 controllers properly on PS5, you're absolutely right that they'll bin these off too..
We're still a good year and a half away from PSVR2, but just a warning that the new PSVR will be using different controllers. It's not been said yet if these Move Controllers will be supported, but given they have now been almost 10+ years in service, I think it's a safe bet to say they will be put out to pasture.
I can’t believe these are still going strong, I still have my ps3 pair and not used for a good while since moved on to bigger abs better things like the Xbox. :)
