There's a guy going by the name fwupow on YouTube who has posted a highly detailed video about the . Apparently these models have already been for sale in Japan, which Rakuten has made possible to purchase. Also eBay has them, but for higher prices. I'm curious to see how the pricing works out once they become officially available to the USA.
CASIO has introduced some really welcome enhancements, especially with the CDT. It is nicely incorporated into the main time display. So, when the CDT is running it will show up in place of the date on the main time display. You can also momentarily check the day/date by pressing the Adjust button, without interrupting the timer. Also, when the timer has stopped, you can momentarily press the Adjust button to see what the time setting is. Lastly, you can kick off the timer quite easily from the main display, just by pressing the "Start" buttton (D). Having the 5th light button makes this possible.
All in all, this module is turning out to be really good. I'm just a bit disappointed that CASIO didn't include any progress beeps on the CDT (which is something that was available on a few previous models). Also, it sounds like the alarm beep tone has not been improved much. At least you have vibration, which is very nice. I also like the fact that this model is not solar/atomic. A robust CR-2032 powers it, so there's no fear of running it dry faster than expected.
