Interesting read about combat, as that's pretty much all that's covered in the article.
Oh yeah and my favorite snippet from it:
"Then there are the grenades. Mass Effect 3 sees a series debut for actual, round, conventional grenades. This adds yet another combat option to the game that changes the way Shepard can engage with enemies, and adds a new tactical wrinkle to flanking and other maneuvers."
Now I don't think they'll be ME 1 grenades considering it says "actual, round, conventional grenades", but certainly anything is better than the non-existent grenades apart from the grenade launcher and grenades from using powers in ME 2 that I found to not be the greatest replacement. At least in my view.
