Samsung has sent out invites for an event next month, with Samsung Premiere 2013 likely to showcase at least two new smartphones.The event is down for 20 June in London and as you might expect, there are no specific details of launches. But the invite does mention the words Galaxy and Ativ. That should mean a new Android and a new Windows Phone being shown off.The Windows Phone launch is a surprise, as nothing has been leaked of late on that front. The Android phones are a very different matter.For a start, we've had the Samsung Galaxy S4 Active leak extensively, even being confirmed by a Samsung exec too, should there be any doubt. That's almost nailed on for the event. But we have also had leaks relating to the Samsung Galaxy S4 Mini, which is, as you expect, a shrunk-down version of the flagship phone.That phone even briefly appeared on Samsung's own site this weekend (before it was hastily pulled), so we can also presume it's a likely launch next month. Which just leaves us with the Windows Phone. But with four weeks to go before launch, there's plenty of time for details of that to leak out.
