It wasn't long ago that the Windows Phone Marketplace hit 50,000 unique titles, and very soon, developers may find themselves with a whole lot more exposure. Microsoft's virtual store is expanding once again -- this time to Argentina, China, Indonesia, Malaysia, Peru and the Philippines. While it's not yet live in these countries, proactive developers may submit their apps now to benefit from early certification. Practically speaking, this also enables Microsoft to have its "shelves" fully stocked come opening day. So, unless you're an odd duck who doesn't like more money, the time seems ripe to get those apps submitted.
