We do know the OnePlus 2 is going to be unveiled on 27 July; we don't know exactly what to expect when it gets here. Fortunately, there are a few people willing to give us a preview.
Take @KJuma on Weibo (the Chinese Twitter), for example - he's provided what he calls a "spy sketch" of what the phone's going to look like. It's not particularly revealing but it's better than nothing.
The tipster also claims the OnePlus 2 is going to feature a screen between 5.5 and 5.7 inches, so it sounds like it might be slightly larger than the 5.5" OnePlus One released to widespread acclaim last year.

We already know from OnePlus itself that the phone is going to feature a USB Type-C connector and will have the Snapdragon 810 processor running everything under the bonnet.
It's not the first early glimpse we've had of the incoming 2015 flagship from OnePlus - users have spied what could be the OnePlus 2 in some promotional materials released by the company.
When the 27th of July rolls around, OnePlus is going to make the launch event available to everyone via the magic of virtual reality. The action starts at 7 p.m. Pacific time, which is 3 a.m. on the 28th in the UK.
