This makes far too much sense for it to not happen.
Shenmue 3 launches next year, finally bringing the main arc of the series to an end. But it is the conclusion to a story that began almost two decades ago- while there many be many fans who remember what happened in the original games, for many, Shenmue is a brand new game, and they have no context as to what led up to the events of the third game.
Which is why a collection of the original two games remastered for modern day consoles would make so much sense. But thus far, an official announcement on that has not been made- although it sounds like one might be in the works anyway.
A Shenmue 1&2 pack appeared for the PS4 and Xbox One on the site of the Czech retailer Alza, and the sites of Slovak retailers Heureka, GetGame and MadGamer (via NeoGAF). The general saying goes, where there is smoke, there is fire- and there’s far too much smoke here to ignore. It seems like a Shenmue collection for both consoles may be in the works after all.
Curiously enough, a PC version is not listed (which is bizarre, since Shenmue 3 is headed to PS4 and PC, but not Xbox One)- that said, there is a possibility that it will be Steam only, which would explain the lack of retailers listing it.
