Samsung's Wave is set to be followed by a host of new mobiles employing the company's proprietary Bada operating system, leaked images suggest.
A slide show of images popped up on the internet this week, apparently after having been shown to developers at a Russian expo.
A total of four Bada-based smartphones are in the works and each appears to be aimed at the lower end of the market, in contrast with the feature-packed Wave.
Two of the phones are touchscreen-only and use a single physical button on the front that is reminiscent of Apple's iPhone.
The other two are full QWERTY/touchscreen hybrids that use slider mechanisms to hide their keypads.
Other Samsung smartphones not using Bada were also showcased, including an intriguing Android mobile and a couple of Windows Mobile offerings.
All About Phones initially published the images, although sadly the non-Bada devices were rather too distant and grainy for any detailed conclusions to be drawn.
Samsung outlined its goal of bringing smartphones to the mass market earlier in the year.
