Interesting topic, it reminded me about something I saw on a French online retailer website,
Alapage (a company owned by France Télécom for the financial blokes among us).
This topic about Wii being worthy of the "next-gen" moniker or not seems to be more than a forum topic of discussion only. The press discussed the topic, barely or badly, as usual with the gaming press; but now it seems that even a retailer is anecdotally confused about the, albeit nothing but symbolic,
next-gen-ness nature of the Nintendo Wii.
It's just a an amusing anecdote, by the way.
Now, with that humorous part put aside, what do I have to say on the subject of the Wii being a "next-gen console" or not?
Simple, it boils down to what definition of a next-gen console do we agree with?
If one believes that a new product released on the public market and which succeed to an older product defines as being a next-generation product, or that the manufacturer of the product is the only one who can declare the nature of their product then yes, the Wii can be called
next-generation.
Now, on the other hand, if someone considers that it takes a technological leap, not necessarily in terms of performances, since it can be architectural first and foremost, between two product to be considered a next generation product and not just a "refresh", then no, the Wii can't be called next-gen, seeing that the its architectural differences and the performance leap over the Gamecube are not not large, nor order of magnitude higher than the previous product.
So, the answer is just that, it's up to each and everyone to decide what they want to consider the Wii. A sizable chunk of the most technological versed folks, not uncommon in the B3D fauna, can be heavily tempted to go with the "if its technology, silicon wise, is not a lot more advanced compared to the product it replaces, then it's a refresh, not a next gen." Just as the gaming versed crowd could go with the "it plays new games, has a different control scheme, thus it's new" motto.
But, the thing is, both are right when described in their own terms.
The sociology fans around there might try to argue, rightfully so, that everything is right when described in their own term. While true in nature, when it comes technology, unlike many other topics, strong consensus do exist. And whereas it would be considered completely preposterous to argue that in
technological term the Xbox 360 and the PS3 are just refreshes of the PS2 and Xbox architecture, with some more RAM added to them, it would be considered as an valid topic, albeit simplistic in itself (and you probably know how much I do not appreciate simplifications when it comes to technology.)
With that said, I agree with the folks who say that it takes more than more performances to be considered "next-gen." Architectural changes are as much important, if not more.
Well, that doesn't help the Wii case, though.
If we take a look to our other favourite subject of discussion here at B3D, the graphical chips and cards, we'll find interesting case studies. For instance, is the very low end part (64bit, cheap and slow RAM, slow clocks, small number of working ALU arrays, low number of ROPs etc...) of a new architecture can be considered "next-gen" when compared to the "last-gen" high end (256bit, fast RAM, lots of it, high speed, lots of working shader cores, high filtrate, etc...)?
There again, a debate could take place, although, personally, even in the unfair case of a comparison between a very low end part and a high end one, I would consider the new architecture as worthy of the term next-gen, even though the real world performances are ridiculous once put side to side with the last-gen high end part. Simply, because the new part represent a (relative, and more often than not, incremental) paradigm shit technologically speaking. Now, of course, it's easier to call something next-gen when it's both architecturally new and perfoms better than the last parts on the market, but it was a point I wanted to address, nevertheless, performances at not all, it's true. Just in Wii case, it doesn't have any to pledge in its favor, when its next-gen nature is argued on a technological level.
The tl;dr sum up
It's up to anyone to decide wether the Wii is next-gen or not. Someone who could follow the cannonical behavior of the technologists, could surely deny the Wii's right to be called "next-gen" and would refer to it as a "new product" or a "refresh." While someone, technologicaly savvy or not, who is more open to the gaming side of it all could be more eager to take things to face value, it's a new console that succeed to another one, it plays new games and it has a new control scheme, and declare that, of course, it's "next-gen," why not?
P.S.: you'll note that I succeed in writting a long post about the possible answer to a question without even responding to it. Awesome, isn't it?
