I think B&H was offering $70 off plus $100 gift card right now. Plus all the Best Buy deals are a great way to get one now. As of right now, there is no date for a new one and my personal opinion is not soon. They still have a ways to go. Maybe Watch S with new material and bands with a full list price.If you are able to get a good deal on one with the Holidays, I would get it now. First of all you could always sell it and put those funds towards the new one. It is possible that they move the Apple Watch to the September release cycle as they did with the iPad when they introduced the iPad 3.
Just my guess. Buy for xmas and save a bunch. The next version may not be worth the difference in price compare to current model I like s lot.
