More than 80% is in support of Segwit so I guess the community is behind the decision and it will be successful.
Well, that's not entirely true since you're referring to SegWit2X. That proposal has the support of the major part of the miners, but not so much in terms of the community and services within the Bitcoin eco system. The community and the core developers stand firm behind the original proposal (BIP141), but due to the fact that miners are blocking activation, things need to be done in a different way, which is often referred to as the UASF. Again, this is something miners aren't willing to support, but in this case there is not much that they can do to block it.
