The first one is already a given, many phones are moving towards 5 inches now, there might a 6 inch Galaxy Note III this year!
iPhone will probably be made bigger just to compete with other phones.
I doubt a 7 inch Surface existing though, although they might to compete with Nexus 7 and iPad Mini.
Again, i'm doubt on Microsoft having a tablet controller for the new Xbox, it's not impossible though
Wii U will sell at least 10 million units i think
Google won't peak until 2015, Apple has peaked though and i think Nokia and Sony are on the rise
iOS probably will be remade but to what exactly?
Since PS4 and Xbox 720 won't launch until late 2013 or even early 2014 in some regions, current gen consoles will be down 20% on 2012 (25% for Wii, 20% for Xbox 360 and 15% for PS3)
My own predictions
PS Vita won't be discontinued at all, there's no doubt about it
3DS will be at least 70% of nintendo's hardware and software sales in 2013
Ouya will sell 5 million units
Steambox won't come out this year
Nvidia's project shield will fail, although the razer edge will succeed despite a very high price
Xbox Series, PS5 and Switch (+ Many Retro Consoles)

Prediction: Switch 2 will outsell the PS5 by 2030
