You won't be getting it. The TS4 logo is a departure from the traditional design, without a plumbob (not that the first installment had one to my knowledge). Audio from the conference call has also been put up on Youtube, so you should check that out as well!
In addition to this the www.http://thesims4.com is now active, although it currently redirects to a page on the TS3 site. Not much else is known about game features although some alleged 'mockups' have been found online tha are supposed to depict what the interface will look like when it's finished.
