HiFi Simulations has finished "Active Sky X" and "XGraphics"
Active Sky X is the new version of the award-winning weather add-on for FS.
XGraphics is a big environment add-on
I have bought both in a bundle and much convinces of both. Besides Global Scenery 2008 X, two another must-have add-on's for me
