For sufficiently vague definitions of Earth. For the definitions being used in most of these sensationalized stories we've already got 2 more we know about, Venus and Mars, and I'm pretty sure if Mercury was picked up in another solar system we'd hear it described as "Earth-like" too, given some of the stuff that has been described that way. The "Earth-like" idea has been debased to uselessness in press releases like this.

Unless they announce that spectroscopy has revealed a lot of O2 in an atmosphere, at this point I'm primed to be pretty underwhelmed.

(And to be clear, I am specifically complaining about the debasing of the term "Earth-like" for PR purposes. The science and discoveries are as incredible as ever, no matter what garbage PR terms are used to describe them in process releases.)

"on the cusp of finding" is a much weaker statement than the current title "Earth-like planet discovered".
