On the contrary, I do.
If you read the article, it says that the game itself is almost like being employed for beta testing. Since players constantly find new information outside of development, that information will be taken into consideration, as well as developer feed back.
If you have ever beta tested a game before, you would know that it requires players to continuously push specific things to find exploits, and since it's almost impossible to do that for a game like smash (this one in particular), having a version available for the masses is the best way to do that. The 3DS version is a glorified beta test for the Wii U version, and while it's a game in it's own right, it extensively serves that purpose. (And perhaps the information found can be patched to the 3DS version via update).
I fully understand what he's saying. Question is do you?
Because the Smash 3DS and Smash Wii U are the same game, obviously the 3DS version is going to be some sort of 'beta test', purely because it's going to be released first, nothing else. Any changes found during this period would also be moved to the Wii U because they are changes for the better. However, this doesn't mean that the 3DS version is strictly 'beta test' material. It just happened to also work that way because
it releases first. That's all. This article doesn't imply what you think it does.
What this article means is just that they can use the same team of debuggers for both games. Both versions are on different consoles, and so testing for both of them is going to be VASTLY different, and so they saw fit to prioritize a version to make it release earlier. It's an issue related to debugging, not a decision purposely made to make the 3DS act as a beta environment.
Again, the 3DS will act as a
pseudo-beta test, but ONLY because it releases first. The article by itself implies nothing. If the Wii U was the version they decided to release first, then the Wii U version would be the one acting as a pseudo-beta environment for the 3DS version, but only as a consequence.
