Some sources are reporting they've got e-mails from Sony, explaining the situation.
This seems to be legit, looks like PSN is going to be renamed on Feb 8, Sony Entertainment Network (SEN) is the name for the new Sony unified online services.
Apparently, the PlayStation Network will be renamed next week. The PSN will now take on the name of Sony Entertainment Network (SEN) on February 8th. This seems to be an attempt to unify all the company online services, and not only the gaming related ones.
This is the e-mail some users are getting since yesterday:
Nothing much will be needed from the user’s end, you'll just have to signing a new Terms of Service.On February 8, 2012, your “PlayStation®Network account” will be renamed a “Sony Entertainment Network account” or a “SEN account” in conjunction with Sony Computer Entertainment’s PlayStation®3 system software and PlayStation®Vita system software updates. (Note, this change will not be applied to the PSP® (PlayStation®Portable) system at this time.)
This transition is based on Sony’s goal to enhance its unique digital entertainment offering. As a series of these activities Sony started last September, PlayStation®Network will be aligned with “Sony Entertainment Network.” This helps us get closer to our goal of establishing a global comprehensive network platform of services across games, movies, music and more, all accessible from one convenient account.
Thank you for your continued loyalty and support during this transition.
The Sony Entertainment Network Team
And the new logo was revealed, as you can see it above. Looks like Sony's plans to restructure the company are starting sooner than expected. So, for now RIP PSN!
