Can I COMPLETE gta 5 BEFORE gta 6 comes out??

So it seems despite racking up THOUSANDS of hours inside of GTA 5 across PS3, Xbox 360, Xbox One and now PC over the years - I've always failed to complete the game 100% of the way. So I've set myself a challenge, with just over a month to go until the big release of GTA 6, I'm going to finally fully complete GTA 5 as a proper send off for the years it's given me.
