I would be VERY disappointed, if the V2 would have an other payment methode like V1.x.
So if you pay 8€ each month, you will pay it for V2, too. As you may know, there will be no more updates to V1, so in theory you could stop paying it every month. But most of us still do this for supporting the V2 development and VaM in general. Like I said: I would be very dissapointed. Maybe MeshedVR could think about a "thankyou" bonus thingy for very loyal supporters, but that is IMHO not neccessary: we all love VaM and this is how patronage works.
