I kind of feel the same and have the similar plans to Snarlz. I also plan to hold onto my 7+ until the X is in my hands. If I don't love the X I'll return it and keep the 7+. Not sure if the 'meh' feeling stems from the to-ing and fro-ing I am having finding a S3 watch I like.
I think I would be the same, but I was silly and sold my 7 Plus before the keynote. I've been using an SE for nearly a month now. Don't get me wrong it's lovely phone, but going from a Plus to SE is a big drop.
I can only blame myself unfortunately.
