Personally I think the snippet is a bit too short for me to decide anything in this case, but I agree: what's the harm in people posting thoughts? Sure, those thoughts will probably change when we get more info... but if that was a proper reason to avoid discussion, then how far are we supposed to take it?
"Oh, we can't judge that song; there's a revamp coming, so it's too early to say based on what we've got. We can't judge this one either, since we haven't heard the live vocals yet; or that one, we don't know how it'll look on stage..." Follow that line of reasoning through to its logical conclusion and this forum would be a very quiet place apart from about one week in May.
