That's incorrect - in general the miners are opposed to SegWit, but they accepted a compromise of agreeing to SegWit if they could increase the block size to 2 MB (from 1 MB currently). SegWit will be activated within 24 hours, but Bitcoin Core (the main developers of current Bitcoin code) have already said they are not going to support an increase to 2 MB blocks. They also claim they never agreed to it in the first place.

As a result, it's very likely to see another hard fork to 2 MB in November, so there will be 3 chains with a shared transaction history, and most like all will claim to be the real Bitcoin -- personally I don't think debating which one is the "real" one is worthwhile, just use the one you want, but eventually it's likely that one chain will get the majority of hashing power and have a much higher price per token than all the others.
