Update: Nintendo Europe has just issued a press release stating that the latest system update for the Nintendo 3DS system will be available in Europe starting June 7.
This will included the e-shop, browser and other features mentioned previously such as the 3DS shop.
Original: Nintendo has announced that at least part of the 3DS update due for late May has now been delayed until June 7.
June 7 also happens to be the date that Nintendo hold’s its E3 conference, although its unclear if the rest of the update, such as the 3DS shop will be delayed until this date, since the announcement specifically mentions the e-shop and the internet browser (which was missing from the list we published yesterday anyway).
Here’s the announcement:
Scheduled for late Orimashita Nintendo e-shop  and [Internet Browser] is available and updates itself will let you know that it will perform June 7.
We will contact Nintendo regarding the update to see if we can find out more.
