Are there any further plans with this project? Further expansion of the hashingpower? Any news or prospectives? 
There has not been any expansion in over a year - and there wont be any more expansion.
Can Leszek or buzzdave confirm this?!
What do you need confirmed? Read the last few pages of the thread. There's no incentive for them to add hashrate much of a year after the mine was increased to the present 500th
