We've been over this a few times, Bercow's ruling last week was relevant - because nothing had changed - so voting on it again was pointless.
Now, with the extension options and what-not it is easier to see how it will be cleared by the speaker for another vote, based on the offer from the EU.
Very possibly. But if it did have the support then Bercow's ruling wouldn't make any difference. It just stops it returning on a speculative basis.
