The Z Fold 7 is CA$1825.
For a phone.
EIGHTEEN HUNDRED AND TWENTY FIVE DOLLARS.
The average world purchase price for a phone is around US$350. This is over FIVE times that.
The G Fold is almost certainly going to be even more expensive.
And people aren't going to be upgrading "just 'cause" every year. This is going to be an impulse purchase for many of the small group who can afford one.
So yeah, I would be reevaluating market demand right now.
