Update on Neo-Pottermore

So, Pottermore's been posting a lot now.  However, a lot of it seems to be copy-paste, but let's see what we can glean from this all. 

Really, the biggest things are perhaps in the second and third post above, as it mentions "news and articles" lending some credence to the idea that Pottermore will be promoting Fantastic Beasts, especially if we see some in-universe material. It also certainly fits with the idea of going beyond the gates of Hogwarts. 

After this, it almost sounds like Pottermore IS confirming that usernames will be gone, and perhaps all the accounts will be deleted, but it's uncertain still. From other posts, it appears dueling and brewing WILL continue past September 9th to an unconfirmed date, and it is probably safe to assume the same may be true of accounts.
