Global software numbers are finally up.
Next week Skyrim may pass up Battlefield 3's total sales on the 360, Forza 4 is doing pretty good (will be close to 2 million by the end of the year)
At this point I think Skyrim on the 360 has a slight chance to sell more than the total sales of Oblivion which stands at 7-8 million + for all platforms it is on. Especially since it looks like Skyrim will have great legs throughout the next year.
