In the light of the latest news, I decided to lift up this thread. As of today, the votes are:
Will Brexit happen on October 31, 2019?
Yes - wjfox, rennerpetey
No - joe00uk, Outlook, Maximus, Erowind, PhoenixRu, Alislaws, Zaphod
Will Brexit happen within next few years?
Yes, sometime in 2019-2020 - wjfox, rennerpetey
Yes, sometime after 2020 - Outlook, Erowind, Zaphod
No, will not happen at all - joe00uk, Maximus, PhoenixRu, Alislaws
So, WjFox and Renner were wrong in first answer but, as it seems from now, they may be right about the second one (I'm not sure they'll be happy with their victory though).
