I hope they do put it out on a blu-ray disc. I am so f*cking fed up with the Xbox 360 holding back game content due to it's storage limitations compared to the PS3. We should be lightyears past f*cking 7GB discs now. If you don't have a blu-ray disc drive, download the game. If you don't have internet, then playing GTA V on PC is the least of your life concerns.
I fail to see why a company would hold content back because of a storage limit on a disc.
GTA 5 will be released on Blu Ray discs for consoles but not PC. It's a waste of money making millions of copies using Blu Ray discs on PC because most people buy their games digitally and out of the ones that don't, they buy DVDs. Why? DVD drives are much more cheaper than blu ray drives and most companies release their content on DVDs.
Trust me, DVDs wont die any time soon. When Windows uses blu ray discs for 2 full versions is when DVDs start to die off. Besides, why release a game that uses Blu Ray discs if you can release it using DVDs which are a lot cheaper for everyone. Just compare the prices of physical games. If you go on Amazon and look at a game and compare the prices of a game on CG and PC the PC version (in the UK) is £10 cheaper and the only difference is the type of disc. Then again, I don't see why you would buy a physical copy of a game for PC... you know... with services like Steam around.
