A new trailer and some info dropped for the new season:

TRAILER

Looks very interesting to me. With a whole new cast and a whole new series director this is verging on reboot territory. If they do go down that road I hope they keep it away from anything familiar for a while. No Daleks, no Cybermen, no ood, all new stuff. Could be a spectacular failure but could also be a really awesome refresh.

They also put out this picture of the new Sonic Screwdriver. It looks a lot less mechanic than any of the other ones I have seen. I don't know how much you can infer from just that but perhaps this Doctor will be more alien than ever before?
