Casey Hudson, project director at BioWare, Mass Effect revealed that 3 is a game much more fun and lighter than the second installment of the series, this in an attempt to ensure that the title brings back the experience entertaining and not so dark gave us the original title, moving away from the heavy issues that were discussed in Mass Effect 2.
"Well, we are not talking much about Mass Effect 3 now, but the second story in a trilogy is where, traditionally, you end up in a fairly dark. The third story is where you try to bring back some fun and lightness.
One thing I try to do with Mass Effect 2 was to bring more mature things, also try to bring more humor to be able to go to these places without making it too heavy experience.
I think we have much more fun this time, with characters like Joker and EDI. Mass Effect 3 will be the epic conclusion ... so, much darker, but also much more humor. "Hudson said.
In addition, it was revealed that sections of mining resources will be back and there will be great DLC bridge between the history of the second and the third part of the story. As to what you mention about the second part of a trilogy, it seems true, but at least Shepard did not end as badly as Luke Skywalker at the end of "The Empire Strikes Back": abandoned in an antenna, without hands and with the worst dad of the galaxy.
