It's tough to say, but leaning towards no. I'm pretty used to my 6 now, and I am still surprisingly smitten with it, but when I pick up my touch 6G it is phenomenal in the hand, even in its PowerSupport Air Jacket.
I suppose the main reason I'm less likely to get it though is because Apple will intentionally gimp it, at which point am I really even upgrading? Money out of my hand, but probably not getting much of an upgrade compared to my 6, if at all. The other reason is that the iPhone 5 form factor is just way too done at this point.
This year I'll have to actually weigh if I want/need a new phone, what with all the carrier nonsense this time around. Normally I'm an every other year launch day guy, but we will have to see this year.
