Unconfirmed: The Witcher 2 Has Sold Over 2.2 Million Copies

We have not received official word from CD Projekt RED (yet?), but according to this forum post citing The Nexus News, the Polish developer's RPG sequel has officially surpassed 2.2 million copies sold following the game's additional availability on Xbox 360/Mac, as well as the various holiday sales.
The Witcher 2 Enhanced Edition was first released on May 2012, it was later released on XBox 360 and Mac in 2012. Before the Mac release the estimates were around 1.7 Million copies in total across PC and XBox Platforms. After the release was expanded to Mac the sales had reached nearly 2 Million in total. Now after the steam and GoG (Good old Games) Holiday sales that had a large 75% discount the sales increased and surpassed 2 Million sales in total, and leave the new estimates somewhere over 2.2 Million copies sold or gifted in total.

This huge sale has increased the anticipation for the upcoming sequel The Witcher 3 which according to rumors it will be released sometime next year (2014).
Here's to hoping that the game has sold at least that many copies, if not more. It certainly deserves all the sales and praise it gets.
