Will NASA revive its shuttles

Answer 1

I think it is unlikely it will ever fly again. But some people do want to revive it. For example, according to glactus in 'SPACE-TALK' thread 'United Space Alliance may keep Shuttle flying':-

'United Space Alliance is pursuing NASA funding to assess the argument for flying the space shuttle for another 12 to 14 missions starting in 2013, after a restart of external fuel tank and solid rocket booster production.

The company is NASA's prime contractor for space shuttle operations and at a forum this week, company officials proposed a commercial shuttle operations strategy. USA is seeking funds through NASA's Commercial Crew Development Round 2 competition to assess the proposal.

This is good news as some space officials believe that tourists taken to Bigelow inflatable habitats attached to the ISS will be a viable commercial endeavor.'

But NASA has said that they will not fly again, so there's no point 'continuing to bang the drum'. They have all been put to museums, parts of them have been removed, and their buildings have been demolished. In addition to this, after about 30 years, the likelihood of accidents happening is probably increasing. Two disasters is enough, and there would be an awful lot of work involved in reviving them anyway.
