SMG went to ofcom some time ago, along with ITN, to propose a pretty radical overhaul of its news output. Basically, the idea was that Scotland Today at 6pm would split at some point (like the Sheena days) with Edinburgh and the East having its own opt. Then at 1030 Scotland, including Grampian and, possibly, Border Scotland would have their own dedicated Scottish news programme, presented from London (stupid, I know). So it looks like they're going ahead with is. They certainly wouldn't create a Scottish East on Sky for ads only as microregional ads just wouldn't pay for the cost of an additional channel
AFAIK they haven't launched yet. I don't think they were ever scheduled to start on Monday, although a lot seemed to take "week commencing 13th June" as being "Monday 13th June" itself. Rumour has it they'll launch on Thursday.
