In a move that could be considered the coup of the decade, which is a very long time in mobile phone years, are we looking at an imminent announcement of the Samsung Galaxy S3?

UK-based retailer Phones 4 U has completely changed the appearance of its Oxford Street branch, covering  the store’s windows with the Samsung logo and the almost ominous announcement ”Coming 30.03.2012.” As you may remember, Phones 4 U was also the exclusive UK retailer for the Samsung Galaxy Nexus, and may have picked up its second big Samsung product in less than a year.

As has been the case for the past month or so, no one has any idea what Samsung is actually up to. There has been no announcement from Samsung about what the product is, and even Phones 4 U is being incredibly secretive about the launch. This has led to conspiracy theorists buzzing about the possibility of this being the Samsung Galaxy S3 launch, which is currently expected to happen only later in April or May.

But this time, there might be some logic behind the endless speculations. There are a few Samsung products in line that could warrant such a marketing strategy, such as the Galaxy Beam, Galaxy Note 10.1, and the Galaxy Pocket, but there have been no tentative release dates announced for any of them. It could also be another variant of the Galaxy Tab series, with the expected arrival of the Galaxy Tab 7.7 or even the Galaxy Tab 11.6. No mid-range product would demand such large scale promotion.

With the tech world slowly getting very excited about the HTC One Series, it would be devious of Samsung to release the Galaxy S3 a full week before the worldwide release of HTC’s flagship lineup. But also incredibly smart. With the  HTC One X expected to be the closest rival to the Galaxy S3, it would definitely be a huge marketing and financial coup for Samsung to release the S3 before the One X. And we already know that the Galaxy S3 is to be released this quarter. Why not sooner rather than later?

Of course, considering the logistics of pulling off such a “sneak attack”, this is most likely NOT the Galaxy S3, but, one can hope, nevertheless. All we know for certain is that Samsung loves to toy with the minds of its fans. Here’s to wishing that this strategy doesn’t end up working against them.

What do you think? Are we finally going to see the Samsung Galaxy S3? Is this another marketing gimmick to launch “just another” Galaxy Tablet? Samsung: enough, already?!
