While I'd agree the description of the emerging church may be vague and varied, no, it's not a fact unless you can empirically back it up. What you said is an anecdotal observation - yours.
Let me pose an overlooked thought, for discussion:
Many believers, particularly those of us who identify ourselves as being pentecostal/charismatic/WOF or what have you, are convinced that what we believe is "it" and that we are on God's "cutting edge", or his latest "move" or "revelation". While we claim to love all our brethren, if we were honest with ourselves, we sometimes think that those in the more traditional or conservative denominations such as Baptists or Lutherans, haven't quite 'arrived' or worse, they've 'missed it'.
So here's the question, somewhat rhetorically: until Jesus returns, is this current charismatic renewal, or movement or _________ (add your own descriptive), "it"?
Is this "it" or is there more to come, until he returns? Or is there the possibility of "more"? And if there is "more", what's it going to look like? And if there is "more", who's going to make the transition to cross over?
These are the questions some of us are wrestling with, when we talk about 'the emergent church' or 'post-charismatic'. Just as many believers didn't make the transition into the charismatic renewal, there will be those of us who will also not make the transition into whatever is 'next' or whatever 'next' is called.
