I think timing mostly depends on battery costs. If lithium batteries continue to drop at present rate, the systems will be available in a few years.

I also think that we will adopt the system's concept gradually. In reality it's already being done in smaller scale.

Some Class Bs already have a second engine-driven high-capacity alternator, large inverter/charger, and large battery bank. And no generator.

These innovative systems have been around at least a couple of years now, and are only limited by battery bank capacity, weight, and cost.

Since most high-end motorhomes will have inverters anyway, and a second alternator doesn't add that much cost (about $400), it comes down mostly to lithium battery bank cost. And at projected costs, 13.5 kW-hours of batteries should be around $4,000, the cost of a typical generator.

Buyers first have to perceive these kinds of systems as superior to generators before they give them a try, but in my opinion that depends greatly on battery bank capacity. That's why lower-cost batteries are so important.
