Blender 2.5 before Siggraph '08?!

I’m watching the Blender Conference 2007 videos right now. I’m finishing the first video, and at about 20:25 Ton is talking about having the event refactor and Blender 2.5 released before Siggraph '08!

Can someone clarify?
Here’s the link to its Google video page.

“Ton will be picking back up the tool api refactor and plans to work on it in Nov/Dec”

I don’t see any issue in keeping up with Siggraph '08…
