I'm only a couple hours in but I agree its an 8.5 imo too.
I think the swordplay could be handled better with a different base deign focussed only on weapon combat, but the way RS2 weaves the gunplay and swordplay together is flawless. I don't know if they could have improved the swordplay without negatively effecting the flow of the game is what I mean, as it is its silky smooth.
Great graphics, zero jaggies on my 42" plasma. Some other awesome stuff going on in the game design too but I wont spoil it for anyone.
Edit: I might go as high as a 9 actually, just for succeeding with a new M+ game design. Have to forgive some stuff to get there but so be it.
