It's a matter of cost and manufacturability ratio. You can get drives now no problem, but at what price?
It's not a "just like a DVD drive". If it were, we would have had Bluray and HDDVD drives for a long time already.
I'm not so sure that's true.
HD-DVD and Blu-Ray have only become neccessary recently, because of the advent of HDTV's. Before this, neither format had any real mass-market appeal, until now. Since the Sony (any many others) will have been producing Blu-Ray lasers for 4 years by the time the PS3 hits, I imagine that's ample time to crank out the technology at a fair rate and price.
