GTA V PC DVD Spotted

In a local DVD Store near my house, i found this it was a packed single DVD with written on it GTAV.
Then i assume that how it can be possible to have GTA V on a single DVD pack on the other hand if we talk about GTA IV then it will be in 4 DVD Pack.

It was clear that it's just an trolling for us.
But unfortunately i didn't buy it as thinking to waste my money on it.

When i talked to the Shop-keeper about it, he said yes it is official, Then i was like lol, How can it possible to have this before the actual launch date plus on an single DVD.
