This is a very good summary, thank you.
I'm glad to hear IPB is considering offering a competitive upgrade, because the time is certainly ripe for it! The vBulletin forums are buzzing like a beehive with angry customers and if IPB was to offer a meaningful discount as well as make it last longer than vB's "special offer" I think that could well be the tipping point that might entice many vB customers to switch. A vB customer with an active licence who doesn't fancy paying $130 now for a product they've never seen will be faced with paying $195 for it later (when it is released). If they could switch to IPB instead for, say, $90 that would be all they need to rationalise their emotional desire to move away from vB, having been screwed over by them. :)
