附上评论区他自己的解释

June 8th is a date that has been rumored for a while, which originated from a Reddit comment of the 2 un-watermarked trailer screenshots. The title of the Imgur album was "60BEB300" and the leaks were posted 2 days after my drawings.
"60BEB300" in hexadecimal is 1623110400 in decimal and 1623110400 is the timestamp for Tuesday, 8 June , 2021. What makes this particularly interesting, is that these leaked images did not feature a watermark, indicating it could have come from someone "higher up".
June 8th not only follows with past EA Play events (as we know that event is pushed pack), but it also falls on a Tuesday, which is a day in which Battlefield usually uploads news etc. As for June 10th, well...
Summer Game Fest retweeting the "Soon, June, Boom" tweet doesn't necessarily mean anything, but Summer Game Fest would be the ideal place to not only replay the trailer, but to have developers answering questions that will undoubtedly come from the reveal trailer.
This is not a leak - This is just my speculation. But the 60BEB300 thing has definitely peaked my interest, as I know those images unwatermaked have come from someone with more access than most.
If this turns out to be true, it also indicates that nothing was actually moved and all along the reveal was intended for June 8th.

简单机翻一下 凑合看

6月8日是一个传闻已久的日子，它源于Reddit对两个未加水印的预告片截图的评论。Imgur专辑的标题是“60BEB300”，泄密是在我的画作发表后两天发布的。“60BEB300”的十六进制是1623110400的十进制，1623110400是2021年6月8日星期二的时间戳。这让人特别感兴趣的是，这些泄密的图片没有水印，这表明它可能来自于某个“更高的”人。6月8日不仅跟在过去的EA游戏事件（我们知道事件是推包），而且它也落在周二，这是战场通常上传新闻的一天，比如6月10日，嗯。。。Summer Game Fest转发“Soon，June，Boom”的微博并不一定意味着什么，但Summer Game Fest将是一个理想的地方，不仅可以重播预告片，还可以让开发者回答毫无疑问将来自揭秘预告片的问题。这不是泄密-这只是我的猜测。但60BEB300的事情肯定已经达到了我的兴趣的顶峰，因为我知道那些未经修饰的图片来自一个比大多数人更容易接近的人。如果这是真的，它也表明实际上没有任何东西被移动，一直以来，揭示是打算在6月8日。

6月肯定要迎来这段闹剧的高潮了
