Coming from Two Tribes' Twitter...

The game now has streaming audio, reducing memory usage and loading times. Sounds the same, much better for our players. The new story advancing section with the 'problem' has now been finalized and looks great. More stuff: more puzzles, world map navigation improved, Toki turns smoothly now, faster water/lava, better looking lights and shadows.

Looking less and less likely that Toki Tori 2 will be available at Wii U launch, but it seems we'll get a better game for waiting. That's perfectly fine by me!
