Pump upgrade do or don't?

I have a Paradigm 722 insulin pump. It is working fine, but has some minor wearing down. I called Medtronics and started the upgrade process. I am looking into getting the CGMS this time. Just not sure this is the right decision. I am thinking of the future. I am still hoping that soon the CGMS and the Insulin Pump will be one unit. My primary ins will cover 80% and secondary should pick up the rest. Also, I have a $500 trade in. Wondering if I should wait and see what the future holds.....
