Tailly, yes they did have DFW in mind when they ordered the ER's but the plan was to have the option for a second Aux tank fitted. The extra 10 tonnes of fuel would have given the aircraft the range to do DFW-SYD but when they did the sums, they found the payload would be too restricted (10 tonnes more fuel means 10 tonnes less pax & baggage).

Sounds a bit like pie in the sky... Whats the market that wants to goto Dallas...
All the businessmen who have connections on AA to 90% of the AA network - that's the market. As two other posters have said, avoiding the nightmare that is LAX and having one less sector makes flights direct to DFW very attractive.
I don't believe that there is going to be a reduction in SFO services in order to fly to DFW. As the Dugong takes over more of the LAX services, there is sufficient capacity in the B744 fleet to do both SFO & DFW.
