Does anyone know if theres anyway to get the new circular icons? I would like to update some of the icons so they match the newer downloads but at the same time, not really wanting to download several gigs just for an icon. Anyone know of anything?

If you're lucky, the games might've been updated in some other way as well, so it's perhaps not only for the icon. But no, short of downloading and extracting the package, you can't get at them (although, it doesn't necessarily have to be you who does the downloading and extracting, might just as well be someone else who sends the icons to you).
