How long does the AI effect last generally?
If it does long enough (let's say until Monday) then the chart after it could be shaken (being night over USA and having the winner just released the song, it's almost a safe bet to assume in the incoming hours he will knock Carly Rae down at least for a while).
I find this all very entertaining: I love when charts shake 
 
EDIT: I also think after the supposed shake-up the one gaining more could be Usher, if he releases a fitting enough video by the middle of next week especially.
Gotye though, given his massive AI and streaming power, has at least 2 more weeks safe at number one (I thought Carly's sales figures would have been stronger... but sure she will have a bigger leap for 
THIS incoming week chart; never enough to dump Gotye down top spot though for a certain while more).
