Saw my first major Bing update last week. I had a handful of my 200 pages in there in a very limited capacity but it looks like a broad index update and page rank update happened the middle of last week.
My keyword rank tracker is also showing an almost on park rank in google vs Bing with positions being relatively near each other. That's a first for me.
Hopefully Bing keeps improving and growing, G needs some competition and duckduck isn't doing it for me
