The Twilight Saga: New Moon' opening day numbers hold strong, so can 'Eclipse' eclipse them?

'The Twilight Saga: Eclipse' - Summit Ent.

There've been quite a few major blockbusters to take the Hollywood spotlight since The Twilight Saga: New Moon. Avatar, for instance, knocked out all prior records with regard to domestic and worldwide box office numbers, and Iron Man 2 had a stellar opening weekend. 
Still, none has touched The Twilight Saga: New Moon's opening day record of $72.7 million, and it's hard to say if and when a film would.
Some have speculated that the only contender for the spot will be this summer's The Twilight Saga: Eclipse.
The back-and-forth about whether Eclipse will outshine its predecessor(s) has been well-documented here, and the gist of the disagreement on the matter stems from Eclipse's temporal location in the year's film release schedule. The argument is that Twilight and New Moon were fall releases and that they had little in the way of competition while Eclipse is a summer release and has more to go up against box-office-wise.
However, some Twilight fans have suggested that it'll be easier to check out the movie in theaters as a summer release than it was to see the prior two.
