Looks like the rumours were false – AndriaSang has posted news from Japan that contradict earlier reports regarding the Nintendo 3DS firmware update, the eShop and the lack of a browser in the bulletpoints.
They’re all coming June 7th, just as E3 starts.
And whilst this is a week later than previously stated (“end of May” was what we were told by Nintendo) it does make sense to launch the new update alongside E3, presumably during or around Nintendo’s press conference for maximum exposure.
We’ve still no details on what games will be included day one with the update (or, indeed, whether this update date extends to Europe) but at least we know the browser will be available.
Roll on E3.
UPDATE: Nintendo Europe has confirmed a 7th June release over here.
