So I did some research and I got a good answer for this.
Obscured, Primed, Fixated, and Drowsy as new Status conditions.
Obscured: Pokemon is concealed in mud, raises evasion
Primed: Pokemon takes a hard hitting stance and increases the damage it deals
Fixated: Pokemon is fixated on the last move it used, and increases the damage that moves does while fixated but also increased damage taken
Drowsy: Pokemon may fail to act, and damage it takes is increased
There was also a tweet mentioning frostbite, which acted like a burn with damage happening at the end of every turn, but I can't find it anymore. And that a new weather condition was also there, something to do with snow (rather than hail), but the tweet is gone.
Edit: the new weather is called snow. Pokemon are more likely to get frostbite, and Drowsy Pokemon are more likely to fail to act. Speed of ice type Pokemon is boosted.
There are also other status conditions, called wild might, terrific might, and terrible might.
For might,terrific might and terrible might no information is given of what they do.
