Unfortunately, that's not true.  The 1307 service from Edinburgh currently runs as an 8-car train from Edinburgh to Gloucester where it splits, with 4 cars continuing to Plymouth and the other 4 cars returning ecs to Central Rivers.  From December, that 4 car unit will continue in service to Cardiff Central where it will stable overnight.  This replaces the 1707 Nottingham to Cardiff Class 170 service which will be truncated to terminate at Gloucester with the unit running ecs back to Birmingham New Street.

The following morning, this 4-car unit will form the 0945 departure from Cardiff Central replacing the current 0945 Cardiff Central to Nottingham Class 170 service which will start at New Street at 1149.  It arrives at New Street at 1145 and the 0628 Penzance to Edinburgh service will attach to the back of it when it arrives at 1156, thus forming an 8-car service north of Birmingham.  However, at present, the 0628 service leaves Penzance as a 4-car unit but is attached to another 4-car unit at Plymouth making an 8-car train from Plymouth to Edinburgh.  This means that the station calls from Plymouth to Bristol Parkway will be made by a 4-car train rather than an 8-car train.

I just went of what I read the allusion was this was a new service

The unit does not stay in Cardiff overnight. In the morning it arrives off the 0649 Derby - Cardiff (between Derby and Birmingham this is a new service). In the evening it forms the 2103 Cardiff - Birmingham before heading onto Central Rivers.

Presumably something else out of Plymouth is strengthened - or one of the existing twin set workings  into Plymouth detaches at New St.

Looks like 1S41 will have the extra set out of Plymouth, detaching at Derby off 1V71 which isn't shown to detach but there seems to be a new 5E71 Derby-Central Rivers at the appropriate time.
