The real mystery is the price of the 70" version.
If you love pulling out old 4:3 VHS movies, this TV isn't for you. If you focus primarily on videogames, this set isn't for you. If you're a movie lover however, you'll find something to love in Vizio's CinemaWide series.
The TVs earn their moniker based on their 21:9 aspect ratio, which comes out to 2.33:1 - essentially the same as the 2.35:1 used in theatrical releases. CinemaWide sets feature a 2560x1080 resolution and upscale Blu-rays to fit.
Vizio has revealed a $3,499 price for the 58" set, though we'll have to wait for pricing on the others. A $3,000 price point on the 50" model would put it in line with the 21:9 offering from Philips. The price for the 70" model is hard to estimate at this point, but don't expect it to be cheap.
