After both Panda & Penguin algorithms, now...

Please watch a video about next update of Google's algorithm for 2013 by Matt Cutts:

An update on Google's webmaster videos - YouTube
Note:
I saw a lot of blogspots got deleted by Google include few blogposts which have high traffic and in the top 50,000 of Alexa.com. I don't understand that why these got deleted. I guess that loads of banner ads on the blogspots which causes this case.

Panda: emphasizes original contents that copyscape 100%
Penguin: diversity - backlink kinds and anchor texts

What do you think about the new update for 2013?
