The modern PlayStation family is now over 100 million strong

Contemporary PlayStation devices have sold over 100 million units worldwide.

The figure comes from a promotional video produced by PlayStation Japan, which you can check out below, and what makes it even more staggering is that it includes PlayStation 3, PS4 and Vita only - not the PS2, PSOne or PSP.

The video is probably intended to woo business partnerships, but as IGN points out, it provides us with an opportunity to do a bit of backwards fact-gathering.

Since we know the PS4 has sold over 7 million units, and the PS3 had over 80 million under its belt at the end of last year, we can deduce Vita sales figures. Conservatively allowing for further sales of PS3 and PS4 since the last announcements, the Vita still seems to have sold about 10 million units worldwide.

Sony doesn't like talking about Vita sales figures, so we're not expecting official confirmation. The Vita has had a troubled life story so far but seems to be doing okay at the moment, with sales higher than Sony's predictions, and may see a boost from the upcoming PS4 bundle - Vita Remote Play with PS4 really is marvellous.
