You bolded the 'BC is an extra' part. Are you saying that you don't agree that BC is an extra, sweet addition that is not part of the XONE?
I am not arguing, or starting a console war ?!? , whatever you mean by that. I am saying that the XONE is a current gen machine just like the PS4, and as such BC is a sweet, free addition that has come along 2 years into it's life as a gift from the XBOX team under Phil Spencer. Having BC does not justify the price of the console, the price of the console is justified anyway.
If you are unwilling to get into current gen gaming because you are waiting for BC then that is either a weird issue that you have, or a financial decision you are making which is right for you at this time.
Just play your last gen games on your last gen console, which they will run better on anyway.
