20GB PlayStation 3 will be upgradeable

Sony has dismissed rumours that the 20GB PS3 will not be compatible with wireless controllers, and that consumers will not have the option to upgrade the hard drive. Sony plans to release a Wi-Fi adaptor for the 20GB PlayStation 3. Consumers will also have the option to purchase a separate adaptor that will allow the use of memory sticks, SD cards and compact flash cards with the machine.
