No, for several reasons.
The main one is that I don't really see the need for such a large screen and it will likely be less convenient to carry in my pocket and hold in my hand.
Then there is the expensive price tag which, given I live in a city plagued by pickpockets, isn't appealing either.
Finally, as I only use my phone for Spotify, Facebook, Whatsapp, Netflix and taking photos, all of the stuff around improved gaming etc. doesn't appeal to me at all.
I guess some people will buy them - perhaps it could act as a replacement for a tablet? Filling the role of both tablet and phone.
But to be honest, it just seems like innovation for its own sake - desperately clutching at straws in an increasingly saturated market.
