I think amazon will be accepting bitcoin in the future cause when alot of people use it they dont want to miss out on money.
This could make them more money since more users will use Amazon because they can use bitcoin, if they don't allow it all those bitcoin users will move to other platforms.
Yes the most people are thinking this and I also think that this will happen but its of course also the question when they will.
I really hope they will do this fast..
