In every project that has cared to mention it, the 2Mbps work has been left to a single phase, and placed as the last phase in the schedule.
I guess it partly comes down to the fact that they don't know exactly where the 2Mbps work will need to be done until they've done all the previous phases - at least done enough detail to be sure of where the actual SF coverage will get to.
I suspect, therefore, that those projects who get their round 2 funding agreed soon enough will then push the 2Mb phase until the end of round 2 deployment.
North Yorkshire was the project with the earliest finish date (Oct 2014, IIRC), so was the one most likely to hit the 2Mb phase first. However, they've recently agreed to add a significant chunk of funding (£8m, mix of BDUK, ERDF and NYCC) which will take an additional year to implement. They hadn't agreed that BT would get the work, last time I looked, but
in this council reportyou can see some interplay with the 2Mb phase whatever happens. That delay takes them to the start of the 2015/16 financial year, so the round 2 funding will be available... and the 2Mbps phase might get pushed back again.
There's an interesting-ish transcript from a Westminster debate on Rural Broadband/North Yorkshire from January:
NY Transcript. It has a little on the 2Mbps/final 5% issue, but nothing of substance - which I think shows both the state of play and the way that politicians expect the 2Mbps issue to continue to be pushed back. A good status update for the SFNY project though.
I also came across some slides from BT, presented to NICC in December, that give a picture of technology options that they think are possibilities for extending SFBB to rural areas, as opposed to the 2Mbps solution (ever heard of an NGA Amplifier?). I imagine every solution that takes NGA deeper becomes a solution that reduces the need for any special 2Mbps solutions.
