Just a thought, but since motorcycles are now in and are, by my assumption, probably lighter than karts I am wondering if there could be a class of vehicle heavier than the karts as well, one along the size of the bigger karts in Double Dash (without being two-seaters of course). I guess you could call it a buggy.
I read through most of this thread and I am surprised at the amount of snaker hate, and especially at who is doing the hating. To me snaking is a skill that one must learn and refine over time, thus making it an advance technique and perfectly viable.
It kind of reminds me of when me and my friends used to play Street Fighter II a lot: we were pretty okay with everything in the game, including throws, which were a very hated part of the game at that time (you would get some cold looks from some of the regulars at the local arcade if you used throws) until I introduced two-in-ones (The act of canceling a standard attack into a special move, guaranteeing that the special move will hit as long as the first strike connected, I do not know what the cool kids call it now days since I have not been in the competitive circles in a long time), which I read about in a Gamepro (they were not THAT bad back then), to the group and at first they were okay with this new technique. That is until one of my other friends and I began to use it as the linchpin to our strategies which made us pretty unbeatable within our little group. Many of the other kids used to say that it was cheating, citing that it was not in the manual and as such was not part of the game. The technique remained controversial within our group for some time, with some learning the technique and using it, while others refused to use it.
I eventually moved away so I do not know what eventually happened within my little group, but the technique has gone on to be put into almost every two dimensional fighter ever made after, and the funny part is that the two lead designers said that the technique was an accident, and was not meant to be in the game (at least in an interview in Gampro, again I must reiterate that they were not that bad at the time). The Two-in-one, arguably one of the things that propelled Street Fighter into greatness, was in fact nothing more than exploit of a glitch.
Now as far as snaking is concerned, I use it, and oddly enough me and my friends came across it independent of any sources while playing Double Dash, and we used it to beat a few of the harder cups, and then we continued to use it within our multiplayer games and nobody cared. Yes, the game "degenerated" into everyone snaking but we were still racing and using items and stuff: the game was still intact. MKDS comes out and I use the technique to beat all the cups on all CC's pretty easily, because that was a self imposed restriction before getting on wi-fi. I do pretty well online using my "secret technique" (at this point I did not even know that it had a name). A while later a go on some message boards just to read what strategies people are using online, just to give myself a little edge and lo-and-behold the internet had exploded in nonstop arguments over snaking. I was surprised that something that I did not think very many people even knew about was the source of so much contraversy.
Looking back after writing that last part I am not really sure where I was going but I typed it all and I do not want to delete it.
Anyway I guess what I am trying to say is that if snaking is still usable and viable in MK Wii I will probably use it, but if it is "fixed" in anyway it will not bother me and I will play the game anyway, maybe eventually finding some other advance technique.
Before anyone starts to call me a hypocrite because of my anti-SSB-tourney rules views, I will say that I have never said anything against advanced techniques, such as wave-dashing, only the actual rules used at tournaments. Just so you know I do not use any advanced techniques in SSB because I have never really had to, but if it gets to that point online with brawl you can bet that I will learn (but not in no item duels, assuming that those kind of options will be available online
).
