Despite all the leaks I'm definitely excited for the reveal today (using my lunch hour to see the event). I currently have a 5A and I'm really happy with it but perhaps in a couple of months I will upgrade.
Regarding the colors, I love black but only when it's matte and based on leaks it seems the black color has some gloss. I'm between the regular 6 in seafoam and the 6 pro in white.
But again, I'm going to wait it out. For flagship priced phones I rather see what the reviews say and whether any hardware issues are later resolved. I don't wish to fork out all this money only to then RMA the device and be sent a refurbished device.
All the best to the early buyers though!
