NeoGaf.com is just a domain name. If what makes it great moves to a new domain then nothing of value is lost.
It's not. It has a name that's well known, a database full of recent gaming history, awesome quotes and threads and had a somehow established "society" that doesn't come from nothing but evolves over years. This is of course also influenced by mods that take care of the society.
A new forum with new mods and a different user base will never be the same, for better or worse.
But seeing that several news sites already talk about resetera, they know how to do pr right at least.
We'll see how it turns out in the end.
