End of summer/new model sale??

With the current rebates I am thinking about pulling the trigger on either a 450 HO or a 570. One dealership I was at said the new models will be introduced soon and in the dealerships by July or August. He said they usually have a good deal on the left over 2016’s once the 17’s are shipped. He didn’t know if it would be as good as the current $1000.00 rebates or not. Curious what your guys past experience is. I’m a total newbie to the ATV game. Is it worth the risk to wait a few months or should I jump on the current rebates that end in a few weeks?
I was originally planning to purchase in a few months because I have one bill I am paying off. I have a decent down payment put back. Once the rebates were announced I was considering buying now to take advantage of the savings.
