Were there any other things involved? Example, Elder Scrolls IV - Skyrim - ran and runs much better on a X360 than a PS3. That would directly effect sales.
Or controller problems? It seem many people preferred the Xbox Controller over the Six-Axis. (Which would have effected Elder Scrolls IV.)
Just curious, as I don't know, what other things might be involved.
Also, look at the exclusives of Assassin’s Creed III - that favored the PS3.
Otherwise, yes it looks like timed exclusives are important.
