Why do you think they'd use crappy ones that break right away leading to endless complaints, customer backlash, and replacements? I don't know who they'd order from, I don't know how it would affect the price, and I don't even think it's that great an idea. But if people want game that's 120+ GB on a physical medium they can use without having to buy extra hardware, that's the best solution I can come up with.
I have many, many boxes of DVDs. I have boxes of VHS tapes, audio cassettes, and vinyl. I have used them never in the last decade. I have DVD and BluRay players, but none hooked up. I have a DVDRW in my desktop, but it's not connected to anything. I have not seen a new computer with an optical drive in years that wasn't a server, and those don't have them anymore either.
From what I can find, the number of computers on the market with an optical drive is probably in the 10-20% range. With no laptops including them, some consumer and business desktops including them, and virtually no gaming computers. No new ones at the least.
And why not? Why bother with them when bandwidth is cheap and USB drives are faster, easier, and rewritable? You don't even need discs for video anymore, what TV can't play off USB?
