Peter Suber has blogged a JISC press release on the funding of 16 large projects.

But will all of them be Open Access?

Definitively no. JISC isn't supporting OA to digitised heritage items.

The National Archives' project on the cabinet papers is - like the other project of this institution ( see http://archiv.twoday.net/stories/2483776/ ) - not OA but toll access (TA):

"Access will be offered through two established routes: via ATHENS,
allowing free access at the point of use for the UK academic sector,
and via pay-per-view payment for other users."

The core literatur on Irland will also TA:

"The Irish Studies Collection will be made freely available to all
users within the British Isles whether the general public, lone
scholars, or institutions. Outside the British Isles JSTOR will
operate their existing subscription model."

"19th century pamphlets online: Phase 1" is also a JSTOR cooperation and thus TA.

The Oxford "Electronic Ephemera" project is a cooperation with ProQuest (ergo TA):

"Any user, anywhere, will have unimpeded access to the high-quality cataloguing information and descriptive metadata that will be created during the course of this project. Members of UK HE and FE institutions, and anyone with access to a public library, will also be given full no-cost access to the entirety of the digital collection."

Once more the PUBLIC DOMAIN will be incarcerated!
