I'll add a bit more to the question. I was on my phone at the time so I didn't want to type everything out if there weren't.
Basically shields, depending on how they are implemented have the possibility of completely changing combat and tactics used. So far it seems only knives and rapiers have been indicated, maybe sabres.
Anyone else see any info I missed? If not, and there just isn't any currently, what are your thoughts?
Why ask? A large family with a shield wall and good teamwork could take out dozens of enemies...
