100% agree it won't be as big as PSP and DS, but I would be willing to bet it will be bigger than the Wii and 360, especially if you can run games off your hard drive because then cost is eliminated. Once you get past a gig, I doubt file size matters for most people since you can start a download before you go to bed and then wake up to a finished download. And then there's ease-- zero modification to your console and will probably be as easy as just dropping an app into your PS3 through a USB stcik and you're done.
Pretty sure that ISPs would kick off about such large downloads, fair usage policies, and all that.
They can bitch all they want, if they're the one that sold you unlimited usage then they're the ones that have to deal with it.
If they sent me a letter like that then I would start downloading nonsense 24/7 completely out of spite.
Well, in the UK (at least), if you break what they deem to be "fair usage" they can do a lot more than send you a letter... like charge you for excess data, cripple your connection, or cut you off altogether.
I'm not sure, but under the Digital Economy Bill, they also will have to turn you over to the respective copyright owners.
