Speaking to VG at a recent London event, Rare senior animator Elissa Miller said that only a fraction of Banjo Kazooie: Nuts & Bolts has been shown so far, and that the game itself is huge.
"There are two entire game worlds that nobody has seen yet - we might be revealing those at Tokyo," she said.
"The thing is, it's such a massive game that what we've shown so far is barely a quarter of the actual experience. It's an immense game, which makes it quite hard to develop, but it also means there's loads to see and do... we've barely touched on it."
