Gold package: ($50/year, I could have sworn I paid $35 for my bros on marketplace. Maybe it was a special for a new customer.)
Wii's system is yet to be fully disclosed. Basically I see better in Opera, but worse in Wii numbers exchange. It should have many of the same additional features due to Wii's use of gamespy's systems.
PS3's system, as advertised, will seem to have everything that Gold offers and more. More interesting Home layout and ability to surf internet.
@omgwtfbbq - sony and nintendo are now also providing the infrastructure. They did not last gen and that is why they both failed at online capability. Nintendo has the system continuously expanding since the launch of the DS's wifi service and sony is now doing the same in prep for Home.
