A tweet later in the day indirectly disputed the 2 year timescale, saying "...£6m investment in new and improved buses for this year...". I suspect one may have been referencing actual years, while the other a financial year which splits across two actual years but I can only speculate on that one.

The £6m appears to include the 7 National Express coaches already delivered and in service (1-7), 2 new single deckers split between Bridlington and Pocklington, 11 new double deckers for Hull and 16 refurbished buses for Scarborough. 

Steven Knight Media has included some more information in their piece on the launch today:

Besides the seven Volvo B11RT/Caetano Levante III vehicles already in service on National Express work two Enviro 200MMCs are on order for Pocklington and Bridlington (we understand these comprise a 10.8m and an 11.8m vehicles. Also due for Hull are 11 Enviro 400MMCs. The E200MMCs and the Enviro 400MMCs will all be built at ADL’s Scarborough site.

A further 16 double deck buses will be rebuilt to as new condition for the Scarborough operation. It is not known if these will be mid-life transfers from other Go Ahead companies or from the existing East Yorkshire fleet.
