In a short blog post about Motorola’s upcoming Moto 360 smartwatch, the well-connected John Gruber caused a stir by seemingly saying Apple will launch “their wrist wearable thing” in September, though he later clarified that his comments were a “joke” and not based on any inside information. While he didn’t go so far as to name drop “iWatch,” Gruber’s post on Daring Fireball leaves little room for interpretation.
