Fortnite Chapter 3 Season 2 leaks from a source that have been right before

Tabor Hill, one of the popular YouTubers, revealed some information about the future of Fortnite.
Tabor Hill is a YouTuber with 1.3 million subscribers. He is a very important figure in the entire Fortnite community because he has been the source of various types of leaks many times. His information does not come from files, but from external sources potentially related to Epic.
Youtuber mentioned two things that are planned for Chapter 2 of Season 3. Influencer points out, however, that, as always, Epic could change plans at some point and it is worth bearing in mind.

It is difficult to say that the 1st season is coming to an end, because only 29% has passed from its beginning. So there are 77 days left. But Tabor Hill is already revealing that one of the motives will be a war with I.O. Perhaps even the main motive, but so far it is not confirmed.
Youtuber mentions heavy equipment that may appear in the game. Including, inter alia, a vehicle with an installed cannon.

These leaks concern the end of season 1 and the beginning of season 2. It is not yet known whether it is strictly about season 2 or the story at the end of the current season. Everything can change as well, which is important to keep in mind.
