I'm not really sure what Bioware means with "polishing" so I'm not even going to bother to read into it much. They seem satisfied with their progress so far and until they tell us otherwise there's no reason for me to stress over it. I was disappointed there was so little at Bioware info at E3 (I wanted a little about the new IP, too) but I liked what little we did get.
People seem do be debating on whether Bioware is lying or not regarding the "polishing" but even if they are what can we do about it? It could be that they're telling the truth, they could be lying, or maybe they're just overly optimistic about their time frame... Or maybe they're telling the truth but what they mean with "polish" is different than what we interpret it as. We have no way of knowing. For me, personally, it doesn't matter. There's too little information to actually speculate about it right now. Instead of pre-emptively deciding the game sucks or will be delayed until kingdom come or whatever, wouldn't it be better to remain neutral? It's not too late to get hyped or to criticize when we've actually seen gameplay or more trailers in a few months time.
I agree it sucks to have to wait so long for more information but at least that information is going to come this year. Even if the game does get delayed again, chances are high it will just be a few months, not a years worth delay, and EA/Boware are unlikely to cancel the game entirely at this stage.
