Do we actually need these teddy bears?

ATM I am farming Ewoks -and I'm not really sure if I am wasting my resources. Are they needed to farm this new Commander Luke or are Ewoks only going to be used for a flash event. What actually has been confirmed?

Nothing has been confirmed, no. But they talk about unlocking Commander Luke being his journey, mirroring the steps Luke takes in the trilogy. Luke doesn't meet the Ewoks until long after he's ever referred to as Commander, so I personally don't think it's likely that we'll see them as a requirement for him.
I would suspect that they'll continue on this hero's journey to the eventually reward us with yet another, more advanced version of Luke (Jedi Luke? Old Luke?), which means the Ewoks are still likely a worthwhile farm for later down the road.
There's also the possibility for another event not related to the release of Commander Luke that will require a squad of Ewoks, so plan accordingly.
