PREDICTION: AT&T's CEO says cellphone plans that count only data usage are likely to come from someone in the industry in the next two years. In such a scenario, phone calls and texts would be considered as just another form of data.

TRENDS: Phone calls have been taking a back seat to other things people do with their smartphones.

THE FINANCES: Phone companies still make most of their money from calling plans and texting, which use very little data. That means phone companies would want to compensate for the revenue fall-off somehow, perhaps by raising data prices.
