I've been following this for a while and I'm dead curious about what they'll find there. It's sad that the well is only a few cm wide (and so deep), making it almost impossible to discover big organisms (fish maybe? Nessie? who knows ...), but even micro-organisms developed totally different to what we know would mean loads to us. It's like exploring a lake on another planet.
Discovering organisms very similar to what we already knew though... that would mean that life on different planets might be very similar to what we see on Earth.
