The official Twitter account of "Tony Hawk's Pro Skater" released a Christmas greeting picture on the 26th, and a detail in the greeting picture triggered concerns about "Tony Hawk's Pro Skater 3 Remastered Edition" guess.
In this tweet, the official released a congratulatory picture with the text "...and Jolly Ollies to ALL". In this congratulatory picture, careful fans discovered a special easter egg in the upper left corner. There is an inequality under the picture frame - "12<312".
Although this equation has no specific background, some fans have speculated on this equation: "12" can be understood as representing "Tony Hawk's Pro Skater 1+2 Remastered Edition", "< "can be seen as "less than" or "to" and "312" may refer to "Tony Hawk's Pro Skater 3 Remastered Edition" or a collection of remastered editions of the first three games.
There is no clear answer to this puzzle. It says "312" instead of "123", which adds to the complexity of the situation. Some believe this means Tony Hawk's Pro Skater 3 Remastered will be bundled with Tony Hawk's Pro Skater 1+2 Remastered, or released as an expansion. Others believe this could mean Tony Hawk's Pro Skater 3 Remastered will be bundled with Tony Hawk's Pro Skater Underground Race and its sequel.
To make things more complicated, Vicarious Visions, the developer of "Tony Hawk's Pro Skater 1+2 Remastered Edition", has now been acquired by Blizzard. It's unlikely they'll be able to produce a new installment in the series any time soon. That said, it's possible that Activision will hand over the project to another studio in 2021.
So far, there has been no official announcement about a new game or a new remake of "Tony Hawk's Pro Skater", and the leaked news is all fan speculation.
