90% sure it'll be 64GB and silver, though still 50:50 on 6 or 6+.
I'm preordering tomorrow afternoon, so I'll probably get it two or three weeks after launch. At least that gives me time to check it out at the Apple Store on release, and cancel it if the other one takes my fancy.
Leaning towards 6+, bit worried about the weight and one handed use though. I'd still like to compose a text with one hand, don't really care about anything else.
