I hope that they consider using other locations around the world. To my knowledge they've used USA and Croatia ( pretending to be Venice ) in Nu Who where the location has been mentioned as part of the story. India would be nice.

Would be nice to see new places ether on earth or other planets. We could also get closure if it is Moffat and JCs last series. Can Clara get a happy ending ?. What about everything that happened in Listen ?. Orson Pink was could or might have been Clara and Danny's future grandson or great grandson. So if he no longer exsists what are the consequences ?. You know in sci fi always a cosmic price to pay. Missy is also rumoured to be returning. How will the doctor and Clara deal with her second time around ?. Could be a lot of fun.
