The price drops suggest a new model may be on the horizon, however if one is released - it will be closer to U3011/apple pricing I would expect - from previous trends.
It is certainly due for an overhaul. Last year saw the U2211H, U2311H replaced and an alternative to the U2410 launched and Dell do like to launch new models in the summer. I think it is the U2711's turn next. It may be much like what happened with the U2410 though - not a replacement as such but an alternative. I would suspect a standard gamut LED backlit model at a lower launch price than the U2711 had.
