First of all, likely no. Top Media is a business company that only wants money. Top Media gave up on UP10TION and want that money money from Jinhyuk and Wooseok. However, UP10TION's 2020 comeback was expensive and they had a 18,000 increase in album sales (The Moment of Illusion - 34,842 to Light Up - 52,048)

in 2020, Jinhyuk and Wooseok are doing acting and were busy while UP10TION are doing nothing besides practicing in the dungeon (dance pratice room), having v-lives, uploading 3-4 fan contents before their comeback and preparing for their comeback. I'm assuming they were very busy between June to November in the dungeon. Sunyoul is also in Voice Trot (whatever u call it), idk much about it. The rest of the members didn't had any schedules besides their comeback.
And Jinhoo, well, from my POV (op POV), he only went on a hiatus cause of his girlfriend controversy or whatever and then went to the military. HOWEVER, he could've went on a hiatus due to health concerts probably but im not buying it. Along to add, Jinhoo had a mini mini fanmeet with a few fans in a cafe back in July. Since he has went to the military and his return date is near UP10TION's contract renewal, I guess it's safe to say he is leaving the group after his renewal (FROM THE OP POV).
Support UP10TION and buy their albums if you can!!
Also, Honey10 we need drama in our lives, i'll start it first
Jinhyuk and Wooseok needs to leave UP10TION, they're not in the group, it has been almost 2 years since they last promoted. honestly leave (i would still support them if they come back)
