Friedcat already said that these arent asicminer. Avalon has around 400MH/s confirmed from users that received the asics so i dont know who that is at ozcoin.
Anyways, let's not talk about a problem we are not even close to have yet. Once we reach 15TH/s bring it up a 5th time.
The fact it's possible necessitates a solid plan. If you don't want to talk about it, that's fine, but I don't understand why others shouldn't be talking about it. Even if it never happens, at a future point I'd like to be able to say that we always had a plan. Also, it's an interesting problem. Most of the talk is about whether the talk about it makes sense, and it's unproductive.
The thing is that was discussed often here. It doesnt matter that it could be possible because it simply wouldnt make sense to attack. The possible gain compared to the gain when the hashingpower is used only for normal mining makes it clear that such thin wont happen. Only someone who isnt interested in money and only wants to hurt bitcoin would try such thing. I highly doubt friedcat is such a person. So the fear about 51%-attack from asicminer is a hypotetical one only.
