Well it's finally official. In a December 14th report, Gamespot has reported that Nintendo has put out their release schedule for the first quarter of 2010. The report has Pokémon Heart Gold and Soul Silver listed with a US release date of March 14th, 2010. As for the European market there is still no official word other than the fact that it's going to be a second quarter release. However seeing that Pokémon Platinum saw it's European release two months to the day after the US release, it may be safe to say that we're currently looking at a May or June release for them.
Let the countdown and pre-orders commence!
