imo they could be on the ipad side if they keep the 1g of ram. But regarding mobile, an iWatch with NFC and payments may be the killer app for that device. I can see myself paying by not taking out anything and just use the watch.
I wish I was.... that being said, we still have to wait on product announcements. Apple is not in trouble yet, I am hoping they will up the ram on ipads for multitasking issues, which will save the games at the same time.
