9to5Mac’s Ben Lovejoy:

Estimating the revenue value of a product whose price is unknown and whose existence hasn’t even been confirmed is probably about as tenuous as it gets, but Morgan Stanley analyst Katy Huberty reckons that the iWatch could generate $17.5 billion in the first twelve months.

To put that into perspective, the iPhone generated $2.5B and the iPad $12B in their respective first 12 months of sales …

So, our estimates of the mythical iWatch’s impact to Apple’s bottom line run from “TOO LOW TO SAVE DOOMED APPLE” and “ZOMG HUGE.”

Seriously, no one has any idea. Just stop.
