Hamilton is obviously nearing his retirement but I would have loved it if he raced for 2 or 3 years more as he is still on his peak form.
But we also have to think in his POV as everyone wants to retire while being the best.
So this teaser from Merc could mean that Kimi could return but once again, nothing is official now. All I can say is that we enjoy Hamilton racing as long as we have the privilege to do so.
