Well, it's Iizuka's decision to keep the current logo or not. But I think the classic "SAY-GAAAAAH" is regarded classic for good reason.
SEGA's opening/end logo's not Iizuka's decision, he isn't SEGA CCO/CEO/COO.
If it's Sonic Team logo's then yes.
So the decision for still using the eye logo still goes to Haruki Satomi, Shuji Utsumi, or Yukio Sugino (Nagoshi was CCO before he departed from SEGA).
But if it were me, I'd go back to the "SAY-GAAAAAH" classic.
