I spent most of my time in the last 2 weeks into translating WooCommerce into dutch (nederlands, nl_NL). Two days ago I made a Git pull request and now it has been included to the core.
WooCommerce 1.2 features the full dutch translation for WooCommerce 1.1.3
WooCommerce 1.2.1 will feature the full dutch translation for version 1.2.1
WooCommerce 1.2 dutch can be downloaded from WordPress.org / Plugins / WooCommerce
