I think the person only means the 2011 september K1 no long accept applications even for new campus? (because earlier it says vaguely on the website that you can call them / write to them to request an application for the Hung Hom campus. It was not written in a very clear manner back then).
For 2012, remember to check the website regularly this August (end of August) and early September about the date of submission and send it out asap to avoid the forms running out.
Hung Hom has no K2 and K3 now. I think they have no plans to have K2 and K3 there in the future too because K2 is pm and K3 is am.
I dont know how many preN are there. But I agree that if there is preN now and they would be promoted to K1 next year, regardless if they can only stay in Hung Hom or can transfer to Kln Tong, the competition would still be larger because the preN can directly go to K1 as I see from the thread.
