I think they meant the current version of the ship. The "E" or "F".
They might have meant that, but it was never specified. Following that proclamation (it might have been Stewart who said it, I can't remember), this board was abuzz about which Enterprise they meant. We knew it was partially misleading, because of the holographic Galaxy class in SFHQ. But the appearance in the new trailer contradicts it. Although in their defense, it's likely part of Picard's dream, which probably zooms in through the Ten Forward windows to him and Data playing poker (haven't seen it yet -- no spoilers, please!). So it's not "really" the Enterprise.
