Nintendo's stock has soared following news that it's holding a major 3DS event in Tokyo on 13th September, just before Tokyo Game Show kicks off.
According to Andriasang, Nintendo is planning on announcing an "extremely big" title around that time - presumably at the Tokyo event.
As noted by Gamasutra, the company's stock shot up 8.4 per cent to Ľ13,100 on news of the conference, which will be confined to trade and media.
Maybe those investors know something we don't. A new Monster Hunter? Pokémon? Dragon Quest? Steel Diver 2? Place your bets.
