One trailer was from before the confirmation, the other was after it was confirmed.

Anime News Network, Crunchyroll and wikipedia confirm that the second season is in fact Black.

The original concept for the second season (Cells at Work!!) was changed during production.

There is currently no actual second season planned for the original series. Black is all we are getting.
