3. More Of The TARDIS
Ever since the show has been back on air, I have wanted to look down all of the TARDIS corridors, peek around the corners, see the swimming pool, visit the old consoles and just explore. The Christmas Invasion showed us the TARDIS wardrobe with its spiral staircase, but that was all until The Doctors Wife, when finally we saw hallways reminiscent of the old hospital corridors of the classic era, as well as the Ninth/Tenth Doctor's Console Room. The potential for episodes entirely on the TARDIS is huge, and I believe Series 7B has a rumoured episode called Journey to the Centre of the TARDIS, so I cant wait.
