Talked with Ryukishi07 about that Rika Times Square moment and he was as surprised as ecstatic when I showed him the video. He did see a pic of it back then, but he thought it was just photoshopped w #Higurashi
Rather than "originally", I should say "at some point in development". It's clear the project went through various conceptual stages, as seen with Hinamizawa Bus Stop among other information.
According to a 2005 interview, Higurashi was originally meant to be a typical visual novel w/ choices where you could do the Rena Route or Mion Route, and after doing both could progress to the Satoshi Route.
Also, Shion was named Tamane & was only later decided to be a twin.
The first trailer for what would eventually be known as Higurashi Gou includes the final line of Keiichi Maebara's letter in Onikakushi-hen - which is never featured in the anime. (2020)
"To the one reading this, please uncover the truth. That is my only wish."
When Higurashi Meguri was first announced it only showed the kanji for "Meguri", which led to many thinking it was called "Jun", the other reading.
It wasn't until this post from Tomato later w/ the pronunciation shown that EN and JP fans alike found out the real name! (2021)
I was looking and I'm not sure how I have bigots following this account. Please do yourself a favor and unfollow before you embarrass yourselves. Block too. Go find a series/creator that doesn't hate all that you stand for.

Meera also translated the original video as shown above and continues to do various work for the WTC community!
Here's an image of the on-screen comments for Gou's ED all saying the line:
"Washi wo shinjite" is a meme in the Japanese Higurashi community, referencing Teppei saying "believe in me" like Rena, joking that he was a good guy all along.
The meme exploded in popularity with Gou, but it actually dates back to 2006 when the anime first released.
