Sorry all... I've been back and forth overseas for family emergencies (so will have no problem hitting Platinum renewal this year, I'd say).
Update is that I called and requested, and was told it was "too early to ask and basically no" as I still had 3 weeks left. As I'm LTG, I honestly didn't want to book a random flight somewhere as I'll always have access to a lounge. In any case, I waited until a week before my status was due and called again, asked, and the lovely agent on the phone told me that the 5 SC had been gifted to me the day earlier! Lo and behold, when I checked my app I had received the 5SC.
