Proof: The Kraken and more.

[Dr. Zeppers]

Indeed it is proof that they are, or at least have worked on it. Proof weve had for sometime now.
There have been kraken images in the phase files for months now, probably over a year.

Developers also tend to leave stuff in the phase files even if they dont use it, not knowing if they might again in the future.
There is definately some old remnants of data/images, etc in the phase files.
Its impossible to determine from the phase files the direction the game is going.
