For the fact that there is a rumour around it shows that its on the table and some of the options to consider. They themselves as an organisations knows about this and that is why they willingly leaked such to the press in other to get the feeling of people and their reactions as well as regulatory agencies. If the good reception is very much more than the backlash, then we should see some implementation around that in the coming days but if otherwise, we still have to wait a long period of time before that will see the light of the day.
I think before the petition was put into action, amazon has already at the back of their mind thinking of bitcoin as a acceptable mode of payment. I think as early as May or June, or maybe earlier than that they are considering bitcoin however when the price pick up they have made the decision to just wait. And when it was petitioned last October, they renewed their interest to see if its fit their business organization goal. However, right now they don't see fit so I guess we have to wait.
