ok that's what I thought - so why is everyone saying "rollback!" if they coudl fix it there then maybe support a 1/2/08 launch?

Why wouldn't they use another type of sensor (just as a backup) when they know they cannot fully trust those sensors currently used.
In part because they don't know that the sensor is the root cause.

Because they may be able to see more data and/or analysis than we can. One of the things they did was add more instrumentation in the orbiter; that might help rule-in/rule-out things that they couldn't rule in or out during the last tanking with this issue on STS-115.

If the managing editor says "Scrub", then it is official. He also reported hearing speculation on a possible rollback. These are from sources "in the know", not just people sitting in front of their computers making it up as they go. As stated previously, this site has direct access to people involved in NASA, and the L2 part of this site has actual, real-time information during the decision-making processes at NASA.
EDIT: redundant comment...

NASA just updated the Space Shuttle page
Approximately 16 minutes into fast fill, two ECO sensors failed to indicate wet. They are troubleshooting the issue. Currently, H2 is at 80% and O2 is at 50%. Tanking is continuing. We expect to have a status from leadership soon as to whether we continue or scrub. If we scrub, a briefing will follow that decision on NASA TV.

Noted it in the article, but should here: One potential plan is to enter the aft, demate and remate the monoball electrical connections to see if bad electrical path.
Remember, it might not be the sensors themselves - especially when these sensors in question are hand picked.

While it is of course disappointing with the scrub (especially when everything else was going so smooth), it's good to see NASA is making the right decision for the safety of crew and vehicle.
I know
I had a bad case of go fever.
