Well, was it the end of Paypal when they decide to want your address and person verification some years ago? No! So Ripple will survive that but it will loses some users which not agree with this procedure.
There will be a lot of people storing money as XRPs who don't want to submit verification details and sell before the deadline. That will probably crash the price. There will also be a lot of bad will from others who don't hear about the deadline and lose their XRPs. The stories those people tell will put ripple in a bad light.
I doubt verification will kill ripple but it won't do it any favors.
