We all know how poorly the PS Vita is doing sales-wise at the moment, so I'm gonna go out on a limb and predict that it will sell under 20m units in lifetime sales. 'Lifetime sales' is quite a loose term; so let's just say that I think it'll sell under 20m units in the next 10 years.
My prediction is based of the fact that I think the PS Vita will struggle to find relevance in today's market, as the boundary between the smartphone market and the handheld gaming market becomes more occluded by the day. Due to this I think it'll continue to struggle sales-wise and it will subsequently be discontinued in the not-so-distant future.
I'll bump this thread on 30th September 2022. In the meantime, do you agree? Do you disagree? If so, why?
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
