I severely doubt both sony and microsoft will have any serious, impending ramifications from any issues or consumer degradation from their consoles both companies were big boys before the console wars (remembering that sony had a big lead on that) I'm sure they can man up and continue with their other avenues.

If people want to play xbox or ps4 exclusive games then they will have to buy one or the other simple as that. And if people hate the xbox one then they can always buy a xbox 360.
Hell they are even releasing a new designed 360, and there are still hundreds of decent games for the 360.
