Research firm Strategy Analytics has published a new forecast sales of video game consoles for several years ahead. It argues that the Sony PlayStation 4 by the end of the decade will go with a circulation of more than 80 million copies. Xbox One from Microsoft if you fall behind, it will buy about 57 million times.

Strategy Analytics engaged in similar research on multiple markets. Experts say that the PlayStation 4 is on the way of repeating the success of the PlayStation 2 and Nintendo Wii". Recall that went on sale in 200 year PlayStation 2 over their entire life cycle has sold over 150 million units.

For the first year of sales of the Sony PlayStation 4 has sold 18.5 million consoles. This number is compared to 20 million PlayStation 2 (2000 and 2001) and 10 million PlayStation 3 (2006 and 2007).

Other analysts, however, believe that the Xbox One, the sales of which hasn't gone so well, can still catch up with the Japanese competitor. According to a report by NPD Group, sales of both next-generation consoles significantly outsell consoles of the previous generation in the same period.
