Microsoft already has a program in place where it will give developers $100 for each app that is published in the Windows Phone Store by the end of June with a limit of $2,000 per developer. But, word has it that Microsoft is setting aside much bigger piles of cash in an effort to attract bigger name app developers, and could end up paying out as much as $100,000 to some app developers to get them to bring apps to WP8.
Of course, Microsoft is no stranger to paying big sums for partnerships, since it is currently paying Nokia about $1 billion per year to be the de facto flagship handset maker for the platform. Given that number, paying out $100,000 to a few developers doesn't seem like much at all.
