Another Sony Ericsson phone launched this week, but once again, the Sony Ericsson Xperia Arc S (pictured) was a single-core rather than the companys first dual-core smartphone. However, news of that next big step has broken, although the Sony Ericsson Nozomi is still some time off.The Xperia Blog claims to have details of the forthcoming Sony Ericsson superphone, although the timescale is rather disappointing. The site believes it will launch in March 2012, not least because March is a favoured month for company launches. The Xperia X10 was launched in March 2010 and the Xperia Arc/Play launched in March 2011. In short, don't expect this to be here anytime soon.Which is a shame, because the proposed specification could really make a dent in the market right now. In six months time? Perhaps not to the same degree. According to those initial reports, an 'insider' claims that the the Sony Ericsson Nozomi will be armed with a 1.5GHz dual-core processor, 1GB of RAM, 32GB internal storage and a hefty 4.3-inch display with 1280x720 resolution. It will also be the first Sony Ericsson phone to come with a micro-SIM and will have no memory card options. Finishing things off will be NFC connectivity and a 1750mAh battery, along with, we presume, whatever version of Android is kicking about then. All of that in March 2012 it would seem. Expect the odd spy shot well ahead of that date.
