I think Ferrari is definitely closing the gap, but I still expect Mercedes to be upfront. Also, Red Bull look to be extremely close to the top two, I definitely see them in the same ballpark with Ferrari, or veeeeery close to them at the very least. I'm actually quite excited that we might just have a three horse race this season, and the competition in midfield might turn out to be the tightest in recent years.
