Any Asics wearers here?

Options
Hi guys,
I've tried a few shoes brands but Asics seem to be the best for me. Use the GT-1000's for walking; have the Kayano 17's for running. My Kayanos are starting to show some wear; I'd say they're about halfway there in terms of mileage - really like the Kayanos so obviously looking to get me a new pair. I hear the 19's are coming out in the masses come January but that they'd be available sometime in November at Specialty running stores.

Should I wait until January and does anyone have the release date for Canadian retailers? I don't really want to buy a set of the 18's if the 19's are coming out in,,,2-3 months y'know?
