I just did the same thing this week. Ordered a 331RETS Premier that will now be a 2016 301RETS North Point. I was waiting to hear when they were going to start taking orders for 2016s. Excited to get it as it will be my first Fifth Wheel. My dealer was told by Jayco that I should expect to receive it by the end of May.
So how long did it actually take to get your new rig? We just ordered a North Point 375bhfs and were told it would be 10 weeks.
