Geez, You think you are so entitled...
You need to look at this from a business perspective. They HAD to move on from the WiiU as soon as possible because the hardware didn't get the attention from other developers like they hoped to. It was a smart choice to hold off on the release of BoTW because that was surely going to kick-start sales of the Switch.
If you have a problem with the way they run their business, do something about it and stop buying their stuff. It's as simple as that.
Yeah maybe I do feel entitled to at least het the same options in purchasing the game as new console buyers but once again Nintendo punishes people for supporting their previoud consoles.
