REL Gibraltar subwoofer

Anyone heard one, own one? Are they even available yet?
Word around the campfire is that they won't be available until August. They were supposedly to have started shipping this month or July, I haven't heard why there has been a delay. If I am remebering right I believe the G1 will be released first then the G2 followed by the G3. I know they designed the cabinets to be able to stack, I beleive to compete with JL(just my thought). My local dealer has a few on order, I'm hoping to hear one as soon as possible.
Update: The first G1s are to arrive in late July. Priced around 4k and should sound like a stentor/studio. Can't wait to hear it.
Anyone have an opinion on these? It's been a year and nothing out there but in-house dealer-reviews.
