Pottermore Insider updates with new info concerning COS development!

The Pottermore Insider blog was recently updated
with a post featuring a promotional video for the
upcoming interactive Harry Potter video game
developed by both Sony and Pottermore,
"Wonderbook: Book of Spells".

It is expected to come out by the end of the year,
most likely sometime during the holiday season.

The Pottermore Insider also made an update concerning the status
of the yet-to-be-launched Chamber of Secrets virtual Pottermore book.

So far only the first of the Harry Potter books has been converted
to the Pottermore virtual experience, with the others promised to be underway.

Here was the update:

Monday 25 June
Chamber of Secrets update:
This week, we’re finalizing artwork for Chapter Seven,  
Mudbloods and Murmurs, and Chapter Fifteen, Aragog.

Cetainly not enough to collect conclusive proof of the Pottermore team's
progress on developing book 2, but well worth mentioning.

Below is the official announcement trailer for "Book of Spells":
