Actually hoping the size is the same . . . I have a lot of money in cases, so I would actually be more likely to upgrade if the dimensions stay the same. Like my rMini, so waiting to see if there is anything to entice me to upgrade.
I have no complaints though. iPad Mini is easier to hold and more portable. But spec-wise, it's pretty stupid to get a rMIni 2. Air 2 is much much better. Processor, wifi, display...basically all that we can immediately feel the benefits of.
