Each of the MER rovers was designed for a 90 Sol operational life. We can certainly hope they last longer but there are no guarantees. They could die tomorrow. So, the focus of current operations is collecting as much data as possible.

If you noticed, they mentioned that Opportunity transmitted back over 145 megabits of data yesterday. Analyzing and making sense of all that data will take time, but that's normal. For example, weeks or even months can go by before an image taken by the Hubble Space Telescope is released. There are issues with calibrating the data, checking it for integrity, and then making sense of it. All of this takes time if you want it done right.
