I know what you mean! I currently have an iPhone 5 32GB I've had for 2 years that I still love. I preordered the iPhone 6 Plus but later cancelled because I had decided it didn't make sense to get a new phone when my 5 serviced me perfectly fine. Ended up changing my mind yet again and preordered another Plus, only to cancel it again the next day after watching first impression vids and reading stuff on here about it being too big! Ended up preordering a regular 6 which is still preordered through Apple, said 7-10 days to ship and it's been about 5 now so should be shipping soon.
However I've been reading through a bunch of stuff on this forum this past few days and it's making me want to cancel again and just keep my iPhone 5 another year or 2. It seems to me that it's probably 100% true that there's something wrong with the camera on all of them in that the edges of things are fuzzy? That really sucks if so because I don't notice that with my iPhone 5 pictures they look great! Really the only things I really want the new one for is the touch ID which I'd use constantly, slo mo video which I'd probably rarely use, and the larger screen which I may find could be annoying since the 5 seems to be perfectly sized. I dunno, it's just so confusing and I don't know what to do!
