It will take more than a few more functionality to make WP8 competitive with Android and ios. Right now it is still playing catch-up unless MS has something spectacular in store which it hasn't announced yet.
A very blanket statement with no supporting basis. It's hard to discuss logically with someone who is so emotionally attached to his pre-conceived notions that nothing else can penetrate.
I would be very surprised if it can gain more than single digit market share in its first year and it won't be enough to keep Nokia alive.
