Do you not think that, just maybe, at the time the recording was made, they were under the impression it was fixed? Or is it just a case of "well it's Microsoft, they always lie"?
Now I dunno about you but before I went before a decent sized multi nation audience I would have made sure it was fixed before declaring it and looking like a chump.
I didn't say it made them liars, but at the very least it makes them look a little amateur.
