I have a feeling this will turn into a hamsterwheel like Sully on the Hudson - did he make the correct choice or not? The (preliminary) numbers seem to show that there was time and distance for an abort, but the crew did not have that info available - it was purely a question of visual judgement for them.
My gut tells me I would have gone for the abort, with a diversion into the grass if necessary (as speed dropped). But I wasn't there, and I don't know that that would have been the better choice, in the final analysis.
In any case, kudos to the A322 crew for sharp reactions, and remembering that you have to firewall the levers, not just the TOGA button.
Not enough info yet to determine why the A333 crew missed the "Stop!" calls and didn't notice the 322 was rolling.
