Archos has updated their G9 pages on their website to mention the Archos G9 1.5 GHz models availability delayed to early 2012.
This delay is probably related to the current unavailability of the TI OMAP 4460 1.5 GHz CPU.
Still, the device do exist as we saw one recently at a recent Paris Android User Group conference where Archos was attending.
We have updated our Archos G9 specifications and prices page to reflect the recent changes in product availability.
Thanks Jbmm.fr for the information.
