My plan is to wait until the 12 comes out, the prices of the 11 Pro's should go down and then buy one of those. Unless there is some *MUST HAVE* feature I can't live without. I'd just like a wide angled lens.
Definitely wait… you'd barely see any difference between your Xr and the 11 anyway. If storage space is the issue, pay for a bigger iCloud plan for a couple of months and offload stuff you don't need on a daily basis.
