Not adding 4GB is a little disappointing. I really haven't seen anything (yet) that makes me want to upgrade my 128 GB 7 Plus, which is still the best iPhone I've ever owned.
I have a 256Gb 7 Plus and it's also the best phone I ever own but I am still looking forward for the 8. Just for the speed boost and the new shape.
Regarding the iPad Pro, I think Apple will go 10.5 inch in 9.7 inch body this year followed by an 8.7 inch in 7.9 inch body and 13.7 inch in 12.9 inch next year.
