What part of 450 million ->new<- devices this year running version 4+ and another in 540 million 2014 don't you get? They are pushing more devices each year than combined total amount of sold iPhones.
Unless apple comes up with something, iOS is not only being overtaken, but run down by a train.

How many of those will run Android 5.0 by December 31?
I would say very few, but it's much more fun to also mention that Samsung has released the Galaxy S II Plus a few weeks ago, is selling it for 5 less than the Nexus 4 in Europe and guess what - It won't get Android 5.0!
That's what life with Android is like.
How many iPhones sold in 2013 will be able run iOS 7 by end of December?
100%!
Even if Google added the most awesome feature you can think of to Android - the huge majority of Android users won't be able to use it until a year later.
And please explain how earning 70% of the profits of ALL mobile phone makers is "being run down by a train"?
In a few years, many of the companies that are making smartphones right now won't exist anymore, because there's only Apple and Samsung making profits.
HTC can't make enough of the HTC One because they lost their tier one status and have to wait for smartphone parts, because other companies are more important.
The "huge marketshare" of Android isn't like that because people using Android devices because they like Android, but because that's the cheap piece of plastic they got for free.
I think Firefox OS is an even worse OS than Android (All power to the cellphone companies!!!), but if it's cheaper for the providers, they'll sell those instead.
If Apple were to make a 199$ iPhone (unsubsidized) - that would be the end of Android winning in marketshare.
But they aren't interested in that kind of marketshare, because if you sold a hundred million devices with a profit of not very much per device - you would earn only "not very much" money in comparison to the money they're earning now, but would trash your margins, something that Wallstreet finds even worse than earning "only" 13 billion dollars in profit per quarter.
So, Apple will be run down by a train that has derailed, crashed and burned.
They'll get a flesh wound, nothing more serious.
