The PlayStation 4 is back on top of the NPD Group sales charts, no doubt thanks to a big showing by the PlayStation 4 Pro.

Four months in a row, Microsoft and the Xbox One had been finding their footing against Sony with the Xbox One Slim. The lull between the announcement of the PlayStation 4 Pro and its release came to an end this month, and it shows that Sony’s update console was enough to rejuvenate its success.

Xbox marketing Vice President Mike Nichols commented on the result, praising the console but unable to use “best-selling” anywhere in his response.

We have seen strong momentum for Xbox One since announcing the new Xbox One S at E3 in June. That momentum continued in November as gaming consoles were once again among the most sought-after products to buy over Black Friday weekend. In addition, we saw record engagement among Xbox One owners on Xbox Live as fans enjoyed new games and great deals. In fact, the total players online on Sunday, Nov. 27 was up 40 percent compared to last year.

Sony only confirmed the news, and it did not offer any further comments. Earlier in the week, the company confirmed that the PlayStation 4 console had broken 50 million units worldwide.

Resurging sales with the new console generation model

If we are going to rebrand the console generation cycles like Sony and Microsoft want to, then this will most likely ping pong back and forth between the two as they release their “upgraded” consoles. Xbox One sales will slow down one the Scorpio is officially shown off, and then it will spike the month of its release. Sony will respond with its upgrade, and this tango will continue to go back and forth.

Back and forth until the end of time.

But when does this console cycle come to an end? You can only reiterate the PlayStation 4 and the Xbox One so many times before it stops being a PlayStation 4 and an Xbox One. I know both are dying to beat out the sales numbers of the PlayStation 2 since that had been a cornerstone of their earlier marketing campaign, but how many iterations of the console is that going to take?

Will either console be recognizable when it comes to that point?
