In the Antares threads it was mentioned that an O2 tank might be swapped out for an N2 tank to replace the one that was just lost.
Just remember that Elon has downplayed chance of first-time success, calling it a 50-50 shot. Also, events like this don't really catch public media attention without video, which may not happen this flight.
When a successful landing happens on the platform located just off the Cape, within range of on-shore video cameras, that will be a big event.

Fill was going to occur on Wednesday or Thursday. I'm told if this thing blows during fill it would damage that end the SSPF, and there were blast shields for the workers to stay behind during the fill just in case.

The barge is located inside the OG2 landing area so SpaceX is using a proven trajectory, ahem, i think i'am gonna watch this flight.
I don't imagine they will try to duplicate that trajectory with the much heavier payload on this mission.
Can't be ruled out though. I would think they'd try to stick to the tried methods for the first landing attempt as much as possible and omit the untested boostback burn. We will have to pay attention to the range and altitude callouts during flight if we don't find out earlier.
Wasn't a boostback done on the CRS-4 mission? So it's not an untested maneuver though not sure if they consider it a success, not much of the first stage return of CRS-4 has been discussed.
And cheers to a fellow estonian on NSF

On the other hand we know that landing in that location can be accomplished without boostback. We'll have to wait and see what will happen. Too early to say boostback is definitely happening IMO.And cheers to a fellow estonian on NSF

Only a guess.
Damages which I think would be quite hard to quantify.
