Silently, Nokia presented to select bloggers and journalist its rumoured replacement for the Lumia 920 during the recently concluded Mobile World Congress in Barcelona. As earlier reported, it's known for now as Catwalk.

Russian blogger Eldar Murtazin, was one of the few people handpicked by Nokia to briefly test drive its next flagship smartphone, which is another Windows Phone 8 handset.

In his blog post, Mr Murtazin offered not too many details about the Lumia upgrade that Nokia is expected to roll out at around the same time the Lumia 920 was let out last year.

One specific enhancement is the body-make as Nokia reportedly is shedding the much of the bulk that the Lumia 920 presented last year. Note that the phone's purely polycarbonate shell made it as the heaviest high-end device last.

It was solid but apparently many consumers looked the other way and Nokia is luring them back by using aluminium material this time for the Catwalk.

"Catwalk will be housed in a slimmer, all-aluminium body," CNET reported the Russian blogger as saying.

He added that Nokia, of course, will bump up the powers that were seen in the 920, which likely will get a faster quad-core CPU and higher screen resolution (given Windows will support the upticks).

Also is expected is the considerable jump in Nokia's PureView camera technology. The company is a cut above the rest in delivering the best camera phone experience last year. But looking at the competition lineup, many were able to catch up with the Finnish mobile phone maker.

Experts expect Nokia to thwart these challengers with the PureView serving via the Catwalk.

Generally, the Nokia Catwalk was nothing short of impressive but Mr Murtazin had one complaint: It would have been better had Nokia tried out the raw power of the Catwalk with Google's Android.

Such proposition, however, is next to impossible. Nokia has declared too many times that its present and future in the mobile device market is anchored on Microsoft's freshly-overhauled mobile platform.
