I could understand if it was months away, but it seems to be only a few weeks away.
Yes, it's theoretically very close, but better be safe than sorry, because things happens.
For example, we are still not 100% sure to do an FS9 version (we always said it's likely, but not *sure*) so, if someone preordered with the intention of using it on FS9 and it wouldn't be released, we would end up in a very bad situation, having to refund lots of money, etc.
