Perhaps most of you are expecting a Samsung Galaxy S3 sometime this year. Many teasers have been posted about the rumored features of the upcoming Galaxy S3, so it’s likely you have been informed somehow of its eventual release. But the yet-to-be-released Nokia Lumia 900 is already expecting a sequel, the Lumia 910, which is likely to be released first for European customers.

According to Typhone, a Dutch retailer, there may be a follow-up to the Lumia 900 Windows Phone that has a list of tantalizing features and improvements over its predecessor. The Lumia 910 is said to feature 21 Mbps 3G Internet connection, a 12-megapixel rear shooter, Windows Phone 7.5 operating system, 1.4 GHz Snapdragon processor and a 4.3-inch display.

Not bad at all, and arguably better than the Lumia 900, which is rumored to be released by AT&T in the US this March. However, it still might fall short of the features rumored to be present in the Galaxy S3, which is expected to be its closest rival in the smartphone market.

This handset, which may see a delayed release – to avoid a long interval between international and US release dates – may ship with Android 4.0 Ice Cream Sandwich, and could also benefit from a quad-core processor under the hood.

The Dutch merchant did not post any possible release date for the 910, but given the fact Nokia will participate in March’s Mobile World Congress, there is a chance we may see a sneak preview in due time.
