The 3DS launched without its online store being ready for business. Which was weird. Weirder still is that the store's launch has now been pushed even further back (if only by a week or so).
A brief announcement on Nintendo's web site states that the online store, originally planned for release in late May, will now be open on June 7 in Japan and Europe. In the US, it'll be on the evening of June 6.
So only a week or two's delay! Which isn't too bad. Well, not any worse than launching a system without its online store working in the first place, anyway.
