Egypt and the PA are openly discarding the carefully crafted 2005 Gaza border agreement without even trying to renegotiate it. It wasn't just an agreement with Israel; it involved the US, EU and Quartet. The value of a Palestinian "agreement" has just plummeted with all of those partners. I would say the chances of a future land-link between Gaza and the West Bank, transiting Israel, are zero. Blatantly violating treaties has consequences.
