There is currently no indication of a second season yet. Those 2009/2010 dates are just people's wild speculation (and pretty nonsensical at that, because no anime tv series is ever scheduled that far in advance).

@anime-dragon: On the contrary, Claymore being licensed increases the chances of there being a second season. This type of dark,violent anime is actually heavily reliant on american licensing if it is to be profitable.
