The internet surely allows the console makers and developers to give the consoles more features and improve performance, and make games better and to deliver more content, but the other way both console makers and game developers have been using the fact that console owners have Internet in order to patch things up because they didn't do it previously is dangerously shifting the burden of annoyance towards the consumer and away from the console makers and developers, that choose to release before, possibly for competitive reasons. They probably think that as long as everybody does it and it's not excessive, they can get away with it, because consumers still have a margin of tolerance.
But there is a major danger they face: I still remember when a game console was just as easy and ready to use as a home appliance, with the added benefit that it was regarded as a technological marvel and a lot of fun. You just had to plug in the cartridge and turn it on. It worked right away, there were never any firmware updates, and games only very rarely had any bugs.
Nowadays, with consoles being more than that, by also having more and more functions of a PC, including all the firmware updates, game patches, the danger is that they may get too close to PCs and eventually become extinct. I remind those who are too young to know, back in the mid eighties and early nineties, there were consoles, and then there was the PC, but there were also two hybrids, all in one computers inside the keyboard, that had better graphics and sound than the PC and were ususally connected to a TV (although they could be connected to a computer monitor), I'm talking about the Atari ST and the Commodore Amiga. As soon as the PC got better graphics and better quality sound (thanks to AdLib and Sound Blaster soundcards), they soon faded away, and by the mid nineties, consoles on one side, and the PC on the other, had won.
