I don't think it's going to change a great deal.
The inner blue circle will be the next circle position, so at the moment, you don't know where the next circle is going to be, so you sit in a building waiting for the next circle to spawn, then head towards it.
In this new test, all this update changes is making the normal circle more contested and will give you knowledge of where to place yourself to be in a good position for the next circle. Luckily, there's a load of buildings and cover in all maps, so people who know the maps well, who can find cover from even the smallest divot will be the best in this mode. Map knowledge will be key. It'll also force people who don't have brilliant map knowledge, to learn to play the sides of mountains and divots better.
I think this is a good update overall, there'll be more action a little earlier on, which is a bit better than having a large mount of teams in the final circle, which can sometimes be overwhelming.
Also, it's 64 players max, just like normal tournaments.
