Yes, SuperDrives are standard on all PC notebook $500 or greater, with one exception, the $1100 Macbook.
As for Blu-ray, it tends to be $150-$200 extra for a standard PC notebook.
I still think it's outrageous for Apple to be selling a notebook at that price with just a ComboDrive. I really thought it would disappear at the last update, but nope. I wouldn't be surprised if they kept it.
