after the other story today about how grave his condition actually was, and the way he looked after 4 does of 'recovery' I think this is going to be a moot point soon.
Well, he's been all but declared dead by the media (and his fellow priests) numerous times. There's no reason to believe he won't have a full recovery.
However... the "several more days" in the hospital scenario is not heartening. The dread fear is that he will contract pneumonia, which is why they don't want him back to his regular duties yet.
It was reported that initially the pope refused to be taken to the hospital. He was ultimately convinced.
At any rate, this is no reason for him to resign. He's not senile. And besides, the only people that demanded the Christ stop being God while He died an agonizing death on the cross were His enemies...
