The way I read it, sellers would still need a merchant account with their bank.
that being the case bank will take their percentage for doing bu***r all and paypal will take their percentage on top
the real point is that the impression I was given when I spoke with all 4 of the 'big' banks is that they are more likely to give merchant facilities to a nigerian internet scam artist then they would to any low life vermin that sells on eBay
