Hey guys.

...Wow, wish I had posted this earlier.

Checked with a friend of mine at Square, and he said it's only a "slight delay," and that the "until the next version update" is a mistranslation of the Japanese news page. Basically, they'll be going in a few days or a week later or whatever, as they've done a few times in the past.

Here's the Japanese text, for those that can read it...
　なお、先日お知らせしました「アトルガンミッション続編の追
　加」と「チョコボ育成」に関しては、検証期間延長のため、次
　回バージョンアップから少し遅れて追加される予定です。追加
　される日程につきましては、追ってニュースなどでお知らせし
　ます。

The important part is the...
次回バージョンアップから少し遅れて追加される予定です

...Which translates roughly to...
"the plan is to supplement the next Version Up a short time later."

Given that this furor seems to stem from, like, a clerical error, what I can't tell you is why the English page hasn't been updated yet.

Hope this puts some minds to rest, or whatever.
