Which is more arrogant / stupid, Sony 2006-7 or MS 2013-14?

Sony 06:
Blu-ray is so awesome, people will take a second job to buy a ps3 and get a blu-ray player $400 cheaper than a standalone one.
Cell is the future, ofcourse developers will be happy to learn how to program efficiently for this akward setup for gaming.

MS '13:
Everyone has internet, always online, all digital is perfect, But we'll still allow some install discs for people with slow internet. And we'll think about a complicated scheme to sell them onwards.
Kinect is so cool, everyone wants to talk to and wave at their console. Nobody will mind a bit weaker hardware and a higher price for this awesomeness.
TV, Skype, sports are the future, but it also plays games!

Both: Our hardcore fanbase will buy our console in droves regardless.

MS was more arrogant in '13.
Sony was more stupid in '06

Sony could not ditch blu-ray or the cell and lost a ton of money.
MS has reversed most of their bad decisions, apart from the weaker hardware.
