For once I agree with Catfllaps, Masterplans are like 5 year plans from recent communist enclaves - a combination of high hopes and little factual content.
Sadly, I can't see the investors at Infratril allowing things to carry on like this, there's a finite amount that they must be allocating to keeping the place going and current income goes nowhere near to coveing real running costs.
I hope not, but the end may very well be nearly nigh.
