Local shops now report that the expansion to Heroes VI - Shades of Darkness - has been delayed.
New release date: May.

No official confirmation as yet on Ubi's main portal, the official forum or the Facebook page - true to their tradition of having a poor communication flow with the Communities.

Also true to tradition is the delay itself. The CH position is that while of course a very boring situation (particularly for those who pre-ordered the game), we do not advocate the premature release of unfinished products. Better delayed and polished than on time and unplayable.
