Writing for Sea Slugs, he mostly spends bytes on retelling, but there's also this:

I wonder if Sword Art Online is one of those Online VR Games that Haruyuki has in his collection.

I saw some crazy cross-overs happen. Of course, Mave-chan was one giant ad for Stratos 4. Then, the bizarre in their shamelessness references to Sacred Blacksmith in Haganai. Things like that. I would not put it past them this time.

Overall, Accel World seems to be shaping like a blockbuster shonen thing that is there to rival best parts of Naruto in intensity. I'm wondering if it's getting good ratings.
