Leather and plastic sleepcovers have indeed been available in FNAC french stores the very same day the Glo was released.
That would be October 3rd or 4th depending on membership.

Additional thought : I have mixed feelings about this cover.
While the touch is indeed smooth and inspires quality, the price is still a bit high regarding the extra functionality.
Auto sleep is nice, but provided it only takes a magnet, I don't really get the whole 45 euros pricing.
Besides, it adds a few inches all around the Glo, making it a bit less tiny than it ought to be.
Touch‘s portfolio was quite equivalent when it comes to the quality feel, while fitting more tightly around the corners, to my taste.
The Glo is now barely fitting in my handbag, plus it's a bit less comfortable to hold when lying on the back (even if it remains completely acceptable, but I do have unusually big hands, too (now that came out wrong...)).

These are nitpicks, arguably, but when you spend that kind of money on accessories, you're obviously expecting something perfect, or nearly so.
