If you mean THIS interview (
https://www.twitch.tv/videos/201749024)
Then I would like to point out the following:
Josh Allan (CM): "We're not talking about WOW classic today. That's just because
we just don't have answers for pretty much anything at this point"
Ion Hazzikostas: "Yeah... <snip> we look forward to awesome
discussion/conversation with the community about what classic means to you <snip> we understand that vanilla means vanilla its about community that means
some of the inconveniences that means
some of the rough edges. Thats not something we're looking to move away from. Its more some of the questions, which version the 2005 or 2006 version..."
Emphasis above to indicate
1) There are no answers yet. It is very very fresh. They are looking to the community to explain what exactly classic means.
2) 'Some' may be intentional or unintentional but if we take it as he said it, then there is the likelihood that there will not be 100% like for like.
Blizzard will listen to the community to get a picture for what classic feels/means. LFR/LFD will NOT go through, given the near universal hate for it. There are clear arguments and logic behind why it kills the community vanilla feel.
That does not extend to every inconvenience
