So based on that - yes, it will affect some iPhone developers, and the argument that this move by Apple is about quality is bogus.
There are many developers that would love to take trade places with those 10 apps in the top 100. If I knew something like Doodle Jump was written on the .NET platform, I'd probably jump at the chance to make a similar clone in hopes of taking it's place.
It's poor business to rewrite an app for no reason. How many months will it take to rewrite these apps just to achieve the exact level of functionality they have now? What if the developer has no Objective-C experience at all (which, given the choice of MonoTouch, might be likely). What a massive waste of time and money for nothing.

On a forum full of developers, this attitude sort of disgusts me. Here are these poor developers having the rug pulled out from the under them but it doesn't matter because we're all replaceable cogs and someone will be there to take their place. That stinks.
It sure does, but it's (unfortunately) probably reality in this situation.
