They won't be 15 dollars, or 50 dollars, most optimisitcally around 100 dollars.
You're basically trying to represent a giant corporation as a starving family man or woman who NEEDS to make the right decision here. Come off it, we're not talking about 'the guy who has to make that 15 dollars work' we're talking about Sony. A huge corporation. Nobody is even saying they need to eat that 15 dollars, but they could get it in there if they wanted to.
Before anyone says "I'm glad I don't have to pay for the thing I wouldn't use" too: You pay for a disc drive, presumably you buy all digital if this doesn't affect you, so why don't you argue about that inclusion? I don't use wifi on my systems, but I understand why we have it and I pay for that part of them too. I don't stand my systems vertically, but some guy was paid to design the internals in a way that it worked like that. We all pay for things that we don't use, at the end of the day this is a tiny additional cost to the system that they could've figured out a way to put in, and not taken a huge out of pocket hit either if they didn't want to. It's not some poor fucking marketing or engineering guy who had to make the hard call to make ends meet for his kids, so don't represent it that way.
