This is why I'm going to move to xenforo, and not upgarding to vb5 when it comes out:

Kier said in an interview:

What are your thoughts on vBulletin 4 and Internet Brand's development on the product?
It's no secret that my team and I were committed to a complete rewrite of the vBulletin code for version four and were waiting to get started on it since the release of vBulletin 3.6. Internet Brands management believed that the rewrite would take too long, favouring instead an approach that kept the 3.x code in place, which they believed would result in a product being brought to market sooner. Who can say what the situation would have been like today had the chosen approach been different.
