If they say its easier I hope it means that the single player has been balanced. One of my issues with the original was that the game was tailored around the 2 player experiences, meaning that some bosses, battles and monsters were easier to take down with two players than with one. It wasn't by any means impossible, but it would have helped to have some advantage in single player.
Regarding Capcom's comment, I agree that they should just have said "UC 2 is in the works, first footage on March 13th". It was a mistake on their behalf, and should be a cautionary tale for both fans and the industry.
But looking at the other side, remember that on-rails shooters weren't a problem with Dead Space was announced. People liked UC and some even wished a sequel would happen so we would get the missing chapters. But after EA dropped the DS bomb how on-rails shooters are a problem, and Capcom hyping up the release was not helping it.
They likely expected fans to be surprised since the first game was a surprise success, and UC 2 hopes to continue that.
