Crossposting, so it doesn't get buried in the Kaz-Gif thread.
Found something in the source code of the german PS site:
http://de.playstation.com/
Code:
<div class="psf" style="left: 35px; margin-left: 10px;">
<img src="/media/114284/Spotlight_logo_platinum.png" alt="" class="ctaLogo"/>
<a href="/meeting2013/" onclick="swfDcsMultiTrackInternal('/meeting2013/', 'WT.ac','PC-de_DE--spotlight-1-M580301-L0-Bleib immer auf dem Laufenden');"><strong class=""><span>Bleib immer auf dem Laufenden</span></strong></a>
<p class="tagline"></p>
</div>
This code snippet represents the spotlight carousel .
the div class of this is named "psf" which could mean they will really name it Playstation Four.
To prove this, the next item in the carousel has "ps3" as div class and contains Trion

efiance (a PS3 game) - so it's an obvious naming convention imho.
tl;dr:
I Hope you get my point
