Appliances debut randomly.

It is not like the automobile industry of old where the new models come out in early fall.

That Whirlpool two oven induction range just came out.

I wouldn't hold my breath.

Sales of old pricier designs going out of production at least for a while, happen in the spring before factories go on summer vacation.
Not fixed in stone every year, but some companies like Sears do tend to push for big sale orders on some of their Kenmore big kitchen appliances in April-May for June delivery. There is sometimes a similar fall wave of intro sales after summer vacation when factories get busy on assembling newer designs.
