What you sceptical about HS2 to Manchester, the route, the timetable?
There is simply no need for HS2 to run north of Lichfield.
A full London to Manchester/Leeds/North Wales/Glasgow service can be worked a re-structured WCML timetable north of Lichfield whilst still running on HS2 south of Lichfield.
Journey time would be slightly longer, but like I've said, there simply isn't the capacity on HS2 for the line to handle service transfered to it from the WCML, MML and ECML.
The Greengage 21 draft timetable shows that there can still be big improvments to services frequencies between London and the North West without the need for HS2 north of Lichfield.
The only other improvements that would be needed would be North Wales Coast electrification and grade speration at Norton Bridge.
Of course, extending HS2 from Lichfield to Manchester would bring journey time savings, but I don't think extending HS2 to Manchester just for the reason would be cost effective. And like I've already said, I believe the principle purpose of HS2 is to act as a by-pass line for the WCML south of Rugby. Journey time time improvements are an added advantage.
So sorry to all those HS2 ethousiasts in the North West, but I just can't see how HS2 to Manchester and Leeds is cost effective. And even if it is built, it will open a huge Pandora's box regarding capacity issues.

Instead of focusing on HS2 to Leeds and Manchester, I'd prefer it if we focused on the development of HS3.
A very rough outline of the route would be something like this;
London terminus at King's Cross (convinient connections to HS1&2)
Line to head out of London in tunnels and runs close to ECML and A1.
Line devides just to the south of Peterborough.
The 'fast line' continues north running roughly along the same route as the ECML with a posible station at Peterboroug.
The 'Loop' then runs westwards through Rutland to a parkway station on the A46 just north of Leicester. It then runs on to an East Midlands Parkway (not to be confiesd with the current station) on the A52 between Deby and Nottingham. Although there may be a case for having this station close to the current East Mids Pkwy for connections to East Midlands airport.
The line would then run onto Sheffield and Leeds before rejoining the fast line in the York area.
Both lines would then join the ECML for continuation to the North East and Scotland.
