Hello, IGN reports the new features of GH5 on the Wii, where is remarkable the first and new "SD card Streaming" , this feature allows to run the music tracks directly without the need to temporaly store in the Wii's 512MBs internal memory. Here is the link:
Also the fully use of HCSD cards is amazing, with this you can download all the songs you want, using a 32GBs HCSD card you can store up to 800+ songs and if you swap the card the posibilities of storage are infinite.
I'm very pleased with this new solution, even far better than the HD xbox360/ps3 storage solution. This means that Nintendo finally catch up the competency and will support mainstream DLC (expasions, adds, patches, etc..) in future Wii games as the other consoles.
You know the DLC we waiting so long is coming and Nintendo will deliver it!!
I hope this means the start to enable new Wii features like: play DVDs, Netfix service, the Manga Channel, download Wii games on demand, improve the Mii channel with new detailed Miis, all the posibilities the new storage allows.
