It is a big deal tbh. Sony may try and pass it off as nothing but they got burned hard on ps3 until really late in it's life and made a big point of telling their investors they wouldn't be doing the same with the ps4.
The fact that they selling at a loss, for what is realistically(in comparison to pc tech) quite expensive internals is purely down to the fact that microsoft played price chicken with them right until the end. I don't doubt that Microsoft is selling theirs at a loss either but Microsoft set Sonys price for them.
Pretending otherwise is just ignoring reality
