Summer Transfers

I know the season has only just finished and everything generally goes quiet for a few weeks on the transfer front - however I was just wondering how the impending takeover (fingers crossed!) impacts our ability to sign or re-sign players?
We are going to need a dozen or more players for next season and the takeover can’t be official until just prior to pre season training commencing. With so many rumours of Sanderson, Trusty etc imminently going elsewhere are we just stuck until the takeover’s complete or can we make movements now? I know players contracts run until the end of June but is the fact we’ve not offered new terms to any of our out of contract players significant?
