Nintendo spokesman and Miyamoto mouth-piece, Bill Trinen, let some
interesting info slide at this year's San Diego Comic-Con. The Legend of
Zelda: Skyward Sword, will allow players to gather rupees and artifacts
to upgrade items like Link's shield and flying beetle device.
"What
I can say is what we've done with the game this time that I think is a
little different is we've built an entire upgrade system into the game,"
Trinen told GameSpot during a gameplay walkthrough. "You can see
right now that Link has his traditional shield, but you actually get a
lot of different shields in the game. You start off with a very basic
one, and as you fight enemies you're recover these treasure or artifacts
that you then use as resources to upgrade your items.
While Trinen didn't confirm other upgradeable weapons, it's probably safe to assuming Link's sword, boomerang, hookshot, and other series staples will enjoy enhancements
