Will it affect the price?
The first of August, 2017 will be the target day in activating the segwit that is intended to come some issues faced by Bitcoin currently. The non-technical Bitcoin users does not really understand the segwit, thus, making then con, pro, or neutral towards its activation. No body is certain if the price will go up or down when the activation come. In my opinion, it is much probable that the price will go up after the activation. Because I believe that the proposal of segwit is for the betterment of Bitcoin.
Though I am still skeptical that segwit will ever be implemented because as of now the consensus of it still is far from the target number, however we might see a sudden boost in support when the time comes. What is so uncertain is how the market will react to the implementation if ever it does get pushed. I just hope it still does go up and not go down because of fears, though if it does go down I would buy a lot myself.
Unless intentions change, there is absolutely enough support. See here: https://coin.dance/blocks
Only 80% is needed with Bip 91 to lock in signaling for Bip 141 Segwit. (see Segwit 2x intention). There will no doubt be drama in discussing the further proposed 2MB fork that would be in November but Segwit is looking pretty damn assured at this point. The debate over the fork should be seen as a strength in how changes are made, but surely will be seen as FUD by most people. Just one more obituary to add to https://99bitcoins.com/obituary-stats/
