It's a bit sweeping to say "there's not a lot commercially that will get in ...." on a runway with an LDA of only 1285m.
After all, LCY doesn't seem to do badly with LDAs of 1319m on both runways.
I take the point though that additional distances are highly desirable and I'm reliably informed that the CAA have approved the plan for a 200m extension without the need to move Eastwoodbury church. RAL probably wanted that approval in the bag before inviting offers for the business.
The Press Release makes specific mention that the proposed extension will permit the commercial operation of types such as the A319 and E195, so I should imagine any prospective buyer will have budgeted for a runway extension before throwing his hat into the ring.
