Downloading wont be around for a very long time.
Average hard drives at the moment for a new computer are around 400 GB to 1TB.
Blue ray discs can hold up to 50GB each. I dont think games will ever use that amount of space but it doesnt take much to fill a 400GB hard drive these days.
I have bought around 20 Xbox 360 games and if each next gen game was to use around 20gb then thats my hard rive used. I wouldnt want to have to keep waiting for a game to redownload. Internet speeds are not likely to perform anywhere near what would be required until 2020 for this type of content.
Discs will stay for quite sometime to come. Be assured.
And if any of the 3 console maker do release a download only console. I probably wouldnt buy it for these reasons.
