Segregated Witness is just another way to centralize mining. I will explain that in the future when I am ready.
... but that is a small price to pay in order to
- Malleability Fixes
- Linear scaling of sighash operations

The technically-challenged will conflate features with don't require Segregated Witness with an argument for why we need Segregated Witness.
Segwit is an elegant way for Bitcoin to gain those benefits. I never said segwit was the only way, but it's good enough and it's happening.
Other coins (like Monero) enjoyed second/late mover advantages by being designed for those features from the beginning.
I heard that the SegWit will be implemented in a few weeks according to the bitcoin core road map. So the price could rise.
Make that a few months, the pull request just came in last week if I recall correctly. It needs to be reviewed thorougly first. Also, bear in mind that it only gets activated if it reaches a 95% treshold of miners running the code.
