Is it a gamble for Apple though? They have such a collection of fanboys that they could release pretty much anything, no matter how shit and there would be a queue around the corner to buy it.
Rather than dicking about with a load of fancy fad features perhaps Apple should dedicate time to finding a phone that does not run out of battery in half a day.
The first company that comes up with a phone you only need to charge once a week will really hit the jackpot.
