Stop worrying Korsan
As was said earlier in this thread Jagex are pooling resources for the launch of a BIG game (Transformers).
They know that PA isnt going to die in the time it takes them to complete that - due to the hardcore memberbase/nostalgic signups.
Yes MarkG should be more vocal on these forums or on NG BUT if he has been pulled onto another project for the present time then its understandable that PA has been forgotten for now.
I personally assume 2 things - that if Spinners game is a success then there is a need for Jagex to overhaul PA to compete with it and that most likely PA was a nostaglic purchase by Jagex (the chances are that some of their team played PA way back when and saw its dire straits and got the company to purchase it to stop it from dying) and will sit ticking over until Jagex is quiet and they have time to look at it properly
