This "breakthrough" has landed with all the bounce of a dead cat. Every newspaper report I've read has emphasised that there is nothing really new is this announcement, and that this has already been rejected - repeatedly - by the Palestinians. Read the comments from Koucher, Clinton, and Mitchell; they all praise it as a "step in the right direction", but none of them hail it as a breakthrough, and none of them have rushed to agree with Israel that "the ball is now in Abbas' court". And the reason why is pretty simple: they have grown weary of making excuses for Israel, and forever pretending that Israeli "half-measures" are "unprecedented breakthroughs". They are monumentally unimpressed, and while they will praise it they are damning it with very faint praise indeed.
