He's right, and it's legitimate to consider the previous works of a developer when considering a new game by them.
Thinking that AvP won't be very good despite lots of evidence to the contrary, including opinions from people who've actually played it, is completely up to him. I'm not being sarcastic or anything; he's entitled to his opinion. It's completely understandable to balk a bit when he's using a track record to support his opinion rather than what we can observe ourselves, though.
