Maybe this is the marketing engine revving up for someone's 'next generation' product. The base model will start off real cheap. Maybe $100 for a launch product. The launch day games will be playable. A few months later, hey, you require 2GB of RAM to play this and only have one. You zip to your local Walmart and find that the extra gigabyte of slow ConsoleRAM is another $100, when you paid that much for four gigabytes of fast PC RAM a year prior. I bet you want Wireless G or N for that too, don't you?
We let everyone access our console by making them cheap! It's totally up to you whether you want to pay the latest and greatest! If not, you can stick to the games that came out last year, but we might even release a patch that makes them require new hardware.
See, this was thought up by a marketing genius. Absolute genius, I tell you. Why don't most people buy consoles more often? A big initial investment for little initial return. You pay $299 for a console, a controller, and a game. A single game. In essence, that game cost you $299. Reduce that to less than the cost of two games alone, and you've got a whole open market. It would also bring PC-style bragging rights into the modern arena. My Console has twelve gigabytes of RAM and a $500 video card, obviously your Console with only four gigabytes and a $200 video card bogs down on Quake 1. It would also take pressure off developers when it comes to optimization. They don't have to sit there for months and take shit from the art department, telling them that they gotta squeeze forty hours of gameplay with huge textures and voice acting and multiplayer and a feature-length making of movie into a single sided DVD (gotta save pennies on the cost!) and make it use no more than a gigabyte of RAM.
