We know Nokia's announcing something at the Build developer event in San Francisco next week, but we're still not sure what – and the event invite doesn't clear things up much either.
However, existing rumours point strongly to the Lumia 630 smartphone breaking cover, and with just days to go before the event kicks off, it's been leaked in a big way over in China.
A series of Lumia 630 promo pics have surfaced over on Winp.cn, revealing it to be – visually at least – a bought-and-paid-for member of the standard Lumia design school, complete with the usual array of colour options to choose from.
The specs, however, give us a bit more to mull over: the Lumia 630 will come with a 4.5in WVGA display (that's a rather disappointing 800 x 480 if you're counting the pixels), while the heavy lifting is taken care of by a 1GHz Snapdragon 400 CPU, helped along by 1GB of RAM.
The internal storage isn't detailed, but we'd bet on 8GB, while the camera is a measly 5MP unit without even a flash.
Probably the most important detail is that the Lumia 630 is likely to be the first handset running Windows Phone 8.1 out of the box. Microsoft's latest OS update is expected to be the star of the show at BUILD next week.
A last word on price – our Chinese chums say the Lumia 630 will be available in mid-April for around CNY1000, which is a touch under £100.
Presumably it's the usual deal about local taxes and subsidies still having to be added, but hopefully we still shouldn't be talking far north of the £100 mark whenever the Lumia 630 makes its UK arrival.
