Well a year is quite a long time, it would be nicer if more of the source had been released by now. But I guess slow but sure is fine as long a Castle don't get cold feet. Personally I will feel more optimistic when all the source is released.
At the end of the day its going to take a number of white knight to come along and devote time and energy developing for free. I have not noticed a great rush so far but I guess its still early days.
At the end of the day my glass is half empty and I remain pessimistic no doubt time will tell.
