Is it stupid to buy the Rift S in the next month or two? I know nothing is ever futureproofed but my mindset is I dont want to spend the full retail price for the Rift S for something to come out in 12-18 months for the same price or slightly more that is much better like the Rift 2 etc. I will mostly be using it for vr porn, Vr cinema movies and some games.
