In early December, Frogwares announced that their game Sherlock Homles: Chapter One was the fastest-selling game in the team's history. There was also a small teaser in the press release: " ... very soon we will make a great surprise for the players on the Nintendo Switch, related to what we have been quietly working on. " It was probably the port of Sherlock Holmes on a portable console from Nintendo.
The other day Frogwares published a New Year's greeting with a holiday version of the illustration for Chpter One. Among other things, there was a picture of the Nintendo Switch with the abbreviation C&P on the screen. You don't need to be known as a Baker Street detective to link a press release teaser and a greeting abbreviation - these are clear hints of a portable version of the game coming soon.
