As an avid Xbox user, what should I do?

I have a library of 400+ on xbox including OG xbox and Xbox 360 titles, now that many people are saying that xbox is going in a downward spiral and people are changing to PC and PS, what options do I have?

I don't want to start collecting on PS, I have already spent thousands on Xbox, I have like 70 games on PS, and trying to rebuild my xbox library is just distressing.

What are my options? Wait for xbox to get better? Or is xbox really done and I have to make the switch before it's too late, any advice?
