Hmm - more "the sky is falling in" posts - not sure why you want to burn points now without any idea of what the new program might be.
Re the "mugs" who might be tempted use some form of "anytime" awards - some people might actually be happy for that. If I was still crediting to QFF I would be at about 400-600K of points at the moment - and I would be happy to burn more points to get a flight whenever I want. I constantly hear about people who have sooo many points and can't find a time to use them - this would be perfect for them.
It is inevitable that points will be devalued over time - perhaps some innovation might create better value in those same points...
