Doctor Who Series 2 Air Month Worked Out?

With the Doctor Who Video Commentaries loosing there episodes on the day that they premiered one year later I think that i've worked out when series 2 of Doctor Who us going to air now this could be nothing but I think it'll air in May as that's when the next video commentary will be removed from BBC Iplayer on the other hand it could also be June as that's when the final Doctor Who: Video Commentary is due to be removed off of BBC Iplayer.
