I believe the quandry is wether a Split 13 episodes = 2 Series (S6 and S7); 1 of 7eps and 1 of 6 OR if it simply means Series 6 has a hiatus.Your posts aren't making sense to me. It's already been confirmed a long time ago that series six is going to be split. What aren't you understanding about that? The episode list you quoted above in your post is simply pointing out the episodes that Moffat is going to be writing. Are you trying to say that because the episode numbers are in sequence to a normal series long production this somehow means the series won't be split?
It has been confirmed by Steven Moffat, Doctor Who Magazine and numerous other sources that episodes one to seven of Series Six will air in the Spring and episodes Eight to Thirteen will air in the Autumn.
There's no quandry as to whether it's two series or one series. It's being shot as one series, it will be promoted as one series and it will be released on DVD as one series. The only quote that referred to the split as being two separate series was made by Steven Moffat when he announced the split and he was merely emphasising the nature of the split as has been made clear in numerous interviews since.
