The only ships flown more than the Eagle are the Sidewinder, Cobra, Viper, Vulture, and Asp and that's with the Eagle's wonderful combination of slow, weak, and fragile.
This new Eagle will probably fix most of the slow, and half of the weak...which means it could easily be a very popular ship, if priced correctly. It could be the new Viper for people that don't like the Viper's slow pitch rate or who can figure out how to leverage the Viper's thrusters...weaker and more fragile, but probably similar speed and more agility.
