Want a pair of Google Glass spectacles? Better get comfortable.

News of Google Glass is everywhere these days, but good luck if you want a pair of the high-tech specs for yourself – the devices may not hit store shelves until well into 2014. That (disappointing) news comes courtesy of Google exec Eric Schmidt, who told the BBC this week that Google still has plenty of testing to do before it's ready to release Glass to the masses. 

"It's fair to say that thousands of [Google Glass headsets] will be in use by developers over the next months," Schmidt said in an interview (hat tip to CNET for the transcription). "And then based on their feedback, we will make some product changes, and it's probably a year-ish away." 

Which is not to say that Google Glass will remain entirely under wraps until then.

Google recently confirmed that the first Glass units were rolling "off the production line" and into the hands of testers. "We’ve been waiting for this day for a long time, and it’s been both thrilling and surreal to watch it happen," Google reps wrote in a Google+ post. "We’re currently notifying our Explorers who signed up at Google I/O 2012, and they’ll be receiving Glass in waves in the coming weeks." 

But Google has also warned testers not to share or sell their Google Glass units, lest they find their devices bricked. 

In related news, Google has released a spec sheet for Google Glass, and all in all, this is looking like a pretty impressive piece of hardware. Among the niceties on Google Glass: a 5-megapixel camera; 12 GB of usable memory, with an option to immediately sync data to Google cloud storage; Wi-Fi and Bluetooth connectivity; and enough battery power for a full day of use.
