Changes to the 350 in March

EYMS, one of the operators of service 350 between Hull, Barton and Scunthorpe via the Humber Bridge, have given notice of changes from 23rd March. This is taken from the VOSA (Vehicle and Operator Service Agency) website.

PB0000328/26 - EAST YORKSHIRE MOTOR SERVICES LTD, 252 ANLABY ROAD, HULL, HU3 2RS
Variation Accepted: Operating between Hull, Ferensway and Scunthorpe Bus Station given service number 350 effective from 23-Mar-2009. To amend Route, Stopping Places and Timetable.

Is this the date for the service to go half hourly Monday to Saturday daytimes, as is expected? In September we reported about the possibility of this, with 3 new buses on order to upgrade most of the Stagecoach workings to low floor status. Since then this order has been reported as being increased to 6, with two vehicles for Hull and 4 for Scunthorpe, meaning a frequency increase looks almost certain. All the extra journeys would be operated by Stagecoach, so are EYMS just going to be making minor alterations to fit in with the enhanced timetable, or are the changes unrelated?
