That's not the upcoming V2 version, it's the current version which was updated with a "2.x" version in 2011 after the initial release in 2008.
That's why we renamed it "Chicago O'Hare 2011 version" on our site, after announcing the new version, so users won't buy it by mistake assuming it was a new version so, apparently, that site has outdated information taken from our site before we renamed the scenery currently on sale as "O'Hare 2011"
And yes, of course, the new version will require P3D 4.4 as the minimum version, so it won't run on anything less, and there will not be a 32 bit version or a non-PBR version.
