Edexcel English Literature Understanding Poetry predictions for May-June 2014?

How likely is it that the poems that have already come up ( in the last four years that the specification has been running) will come up again this year? For Clashes and Collisions, no poem has been repeated, meaning 10 out of the 15 poems have already come up in section A and B combined, narrowing down considerably the range that could come up again, if the exam board decided NOT to repeat any of the previous ones.

Anybody else going to use this strategy, or is everybody revising all 15 of the poems in equal depth?
