I totally agree with most of your points. I think the integrated BR-Player is an important point for many customers of the PS3.
I think customers who only look for games and have a good view over the console market will still prefer the Xbox360, at least in most cases (me prefered the PS3 because of my special taste in games + have a good PC). Thats why the software attachmentrate is comparatively bigger on the Xbox -most of the "real"-gamers bought one. So you can call the BR-Player a disadvantage compared to the "hardcoregamer" image of the Xbox, at least for software sales.
But in the end only the mass-market count and those people don't read forums etc. They only choose cause of brandname and of course the price. I think a casual will more likely know that a PS3 can play BR than that the Xbox have more/better games for his liking.
And that is why I see the Xbox on #3 at the end of this generation, they won't manage to make the Xbox-brand as big and popular worldwide as the PS-brand, at least not in this gen.
btw, I think you should use some breaks in your Text, ll make it a lot easier to read and understand (:
