Um ... it's down from 1.5 on the eve of the referendum. In what world would it not rise? The longer it stays low, the more the price will rise ... and, news flash, it isn't going to go back up.
Even if 'Brexit' is kicked into the grass fairly soon, we're not going to avoid a recession (too late), and serious damage will have been inflicted on Sterling / $ anyway.
If 'Brexit' is followed through and it looks like we're going to leave, £ will fall to parity with the $ very quickly. At that point you can probably expect a 1080 to cost ~£900 with current pricing schemes.
