Apocalyptical gaming preachers keep on yelling the unaware and unwashed sinners that with WiiFit, Wii'll have the final weapon to disrupt hardcore gaming.

What they seem not to realize is that thanks to increased gamers awareness of fitness, the fitness itself made easier and amusing, and also the total body activity in front of the TV, instead of lazy immobility could bring disruption outside the gaming industry: WiiFit could disrupt USA and also rest of world JUNK FOOD INDUSTRIES!!!

Obviously Soylent Green will be unaffected...

Update: it could disrupt broadcast TV too! Each time the networks won't transmit programs good enough, family, thanks to the broad appeal of Wii, could skip them for a game together, skipping with them, the horror!, commercials too.
Wii could disrupt ADVERTISING!

ummm... errr... is this the right time to... blame... WiiFit?

Don't you know? It's ALWAYS the right time to blame Wii and WiiFit!   

ZOMFG! I didn't realize how much so far: all those people waggling and jumping on the boards, tsunamis, earthquakes...

People will get bored and maybe go outside and buy some junk food to reconnect to the rest of the human society. Wii will then be a major fad :) Wii fit will become what every other wonder exercise equipment becomes... in the cupboard and forgotten. Let the fad countdown begin :D

 Good thing that there are so many other games set to support the balance board, then.

Uhm, perhaps I see another point in your phrase: yes, Oprah and the others, all that ads and blabbing frenzy on TV thanks to WiiFit, yes, but, after the families get the message and buy the dreaful weapon of evil , the desert, that will be the swansong.

 Maybe. Or Maybe junk food will become snobbish stuff. 

@Fam - maybe but how long will it hold peoples interest. Sure I'm only having a dig and a bit of fun, but in reality people have good intentions and then life goes on with family, work etc and its forgotten. The only peripheral that will always be relied on is the controller :D all others are forgotten.

Wii fit will and is big and will last a while, but it won't disrupt anything like the poster said. Well, maybe the posters brain which seems to be happening :P

Who can resist jumping on the big disruption buzzword bandwagon???   

...And I don't even have a Wii, yet!
