That's entirely dependent on if the leg beyond Birmingham gets built. The East Midlands/Leeds line of HS2 has already been scrapped and the Birmingham/East Midlands line is also seemingly being considered to be axed.
It's already been said that Manchester's HS2 station won't be buried underground due to the paltry (in the context of the entire project) cost of £5Bn being too high. Plenty of stink has been, and will continue to be, kicked up over that decision.
With the costs constantly rising and work on the Manchester branch not expected to begin for another decade, it wouldn't surprise me if HS2 stops at Birmingham and the rest of the project is binned off for something cheaper and half arsed.
