AFAIK DVD Player is still in OS X Mountain Lion with no plans to take it out.
Pop a DVD in a Mac and it just works. Not the special edition OS X, just the regular one.
With that said, most people use either iTunes, Amazon on Demand, Vudu, or PSN to rent movies. Still, Mac does media way better, and as much as Steven wants to copy Apple, he's not willing to go the last 10%, just like Bill Gates wasn't on Windows 1.0. Unfortunately it's no longer 1985 and people can tell the difference now.
Enjoy your corner cutting masterpiece.
Like it really matters. Apple's pretty much taken the DVD drive out of all of their notebooks. The 3 people who bought their Mac Pro desktop will certainly enjoy playing DVDs on their computers.
