Well they're still going to do some of the OMGIGP references (or so they say) but honestly, lets think on this Microsoft. You've seen a Family Guy episode - you ask them to create one to help brand your product, and then you're offended because they included "off color" jokes? Oh come now, who was the creative genius behind that idea!
Just like Microsoft wouldn't approach SouthPark for fear of bad press, the same should have been expected with Family Guy!
And why, if Family Guy is too much for them to brand for the episode, but it's OK to do a 12 week college tour with Family Guy characters and the Windows 7 platform? So it's OK for smaller audiences, just don't let the media find out?
I like Family Guy - will be interesting to see what gets leaked online since the episode is already completed and was screened by MS Execs.
