The multiplayer in ME3 has had a seemingly polarizing effect, even though very little is actually known about it. The general concern seems to be that Bioware is losing focus from a story-focused game, whether it be resources or otherwise. By the way, regardless of what you think about any of this, this is the same strategy that has made Mass Effect the franchise that it is today. Given that, I definitely understand the concern. Also, Bioware's announcement seemed somewhat apologetic, as though they new people would be concerned. "Here's this great new thing, but don't worry, it won't effect the quality of the great old thing." Not exactly inspiring or confident, but whatever.

I sincerely doubt that Bioware actively decide to divert anything that would make ME3 anything less than awesome. At this point, who is to say that this decision has had a detrimental effect on anything? My only real wish here is that gamers, as a culture, would exercise a little more maturity and actually reserve judgement until they receive a final product.
