Actually,i found it accidently in a greek forum 'bout Syphon Filter,i cant traslate you everything in the forum but in a general view,Greek Ppl also believe and trust their state: That a NEW SF 4 will come for the PSVita Device..
Okay i found the video,but unfortunatly must tolerate that its not an ordinary Teaser ...
Its a unique one because it hasnt anything except from a black screen with Morse Code..
I have studied for Morse Codes and i encrypted alone because i dont trust the comments in YouTube lol and i also used a program which converts the morse code into letters just to be 100% for what i've found in that code...
Syphon Filter 4 Teaser
Morse Code:
LOGAN RETURNS stop TASER RETURNS stop REST CLASSIFIED stop MOVE stop SHARPSHOOTER SUPPORT.
Sorry for my bad English ...
