When could we see the digital dashboards?

Jamie McMurray recently posted a picture on his Twitter account displaying a test of a new digital dashboard for the NASCAR top series vehicles. But when will they replace the old traditional dashboards that have been used in some form or another ever since NASCAR's establishment? And are they going to be more hype than reality? Or will they actually be a useful tool for the sport? Given all of the technologies, electronic and not, that have improved NASCAR over the years, especially the modern-day digital scoring systems, it's likely that digital dashboards will actually come in handy in the sport in the next couple of years.
