No chance. That's not going to happen.
But that's not really the question to ask. The right questions are,
- what are the chances that my tastes and needs may change, making me wish I'd gotten something else, or nothing? (high)
- what are the odds something else good will be on sale then? (100% - there's always something on sale if you can wait a few months)
- what am I going to do with all these huge boxes in the meantime?
Buying HT and audio gear for distant future use is a bad bet. It's hard enough to get the right stuff now, as you can see from all the threads posted by people that can (or should be able to) know their needs, uses, tastes, room, layout, budget, family situation, etc.
