This does look like a classic case of pump and dump. The interview really didn't say anything new that was unknown but people took the news as "asicminer is going to have 1000th/s solo mining" instead of "asicminer will have sold a total of 1000th/s"

According to my calculations (@30%apr) asicminer should be hashing at around 250 th/s to be valued at 1btc/share (currently at 50th/s). And for that to be true we would need to expect constant hash rate growth along with the difficulty increase which doesn't seem to be happening.
