Rogers was the first carrier in North America to offer the Sony Ericsson Xperia X10 so it's only likely that they'd also get first crack at the X10 Mini and X10 Mini Pro. Somehow, the carrier accidentally spilled some beans showing they will be doing exactly that.
According to RGB Filter, the Rogers on Demand mobile (ROD Mobile) app page has a pop up window that shows compatible devices. Clicking on "available devices" yields a list of phone running among other things, Android 1.6 handsets. Both a Sony Ericsson E10a Robyn and Sony Ericsson E10a Pro Mimmi are listed there yet neither are available from Rogers as of yet. It doesn't take a rocket scientist to figure out what is going to happen soon.
