It is just speculation on my part, but I think the reason the phenomenon of releasing new works within a franchise without any version number or title suffix is that the marketing people may be of the opinion that some people may not want to see a movie or play a video game of a higher version number if they have not already played all of the ones that came before that. I know this seems silly because just using version numbers even once would seem to indicate that they were ok with it before so why not now? I think this is answered simply by having people either change their mind over time, or entirely different people making the decisions and deciding the marketing of a given title on its own merits with their own criterion, so seemingly irrational decisions can happen purely for marketing purposes.
It might end up being a genuine sequel, or it might end up being a remake of the original or some other previous release, or a complete reboot/re-imagining or something else. What's more annoying is if they make a sequel to that later and call it "2" when there is already a former "2" from the original series. :)
In the case of Rambo, there were a very great many years that passed by since Rambo 3 to the new Rambo movie, and calling it Rambo 4 may perhaps have alienated some potential viewers, in particular young people that may have not even been alive yet when the original trilogy was fresh. Calling it "Rambo" in marketing sense makes it seem like a fresh new movie without pinning it psychologically as a sequel to the originals.
In short though, all of the cases where this happens are 100% pure marketing gimmicks. Similar happened with the Tomb Raider franchise, Thief, Wolfenstein, and now DOOM as well. It's like a "fresh start" for the franchise name psychologically.
What's funny is watching how things like Microsoft Windows version marketing has evolved over time.
Windows 3.1 -> Windows 95 -> Windows 98 -> Windows 98SE -> Windows ME -> Windows XP -> Windows Vista -> Windows 7 -> Windows 8 -> Windows 8.1 -> Windows 10.
Not only that, but the internal version of the operating system that Windows reports to programs that query it is completely different than the end user visible version number if it sports a number. WTF is that all about? Marketing appeal, that's what. And why is there no Windows 9? (Don't answer, I know the answer already... :)
In the end, it's all about the psychology of marketing marketing marketing. :)
