i don't think they are going to embrace bitcoin this soon, they may be scared of being removed from the scene and lose their position if bitcoin becomes popular so they may want a piece of the action. but it is unlikely that they do it at this point.
sure,they seems just doing cooperation with coinbase nor with bitcoin,and bitcoin have nothing to do with it,just a business relation between 2 companies so couldn't say paypal fully accept bitcoin to be part of them
maybe next time they will but they need to learn deeply about bitcoin first and prevent any kind of unnecessary things
