GoogleGuy says that the new index was crawled by the bot formerly known as Freshbot. He also confirms that the bot formerly known as Deepbot will probably not be seen again (using the Deepbot IP range). Link to quote

"Ahem, GG, does that mean we will see an actual deepcrawl again?"
If you're asking whether you'll see crawls from the IP range formerly known as deepbot, I would say "probably not." If you're asking whether we'll continue to deeply crawl and index the web, then the answer is "definitely yes."
Hopefully that makes sense. The index that's coming out now was crawled by what people call freshbot. But freshbot can crawl deeply too. It would make more sense for people to rename it deepfreshbot. :)
