Sure, paypal is the big kid on the block right now, but who's to say they won't start accepting bitcoin as one of many international currencies?
(Edit: I just added "after 5 years" and "never" as additional poll choices.)
It will take more than 5 years before Paypal accept bitcoin because Paypal is directly competitor of Bitcoin in terms of payment not only offshore but also in local payment. If Bitcoin is already more than 50% adopted all over the world, maybe PayPal will accept it.
