Sony is on pace to strike first in the 4K console war after unveiling a more powerful version of its PlayStation 4 earlier this week. The PlayStation 4 Pro packs a faster processor, better graphics and support for 4K resolution and HDR. Netflix is even working on an app that’ll allow Pro owners to stream video in 4K quality.

Sounds impressive, right? Not according to Microsoft.

The Redmond-based company took to Twitter shortly after Sony unveiled the PlayStation 4 Pro to tout its Xbox One S. It seems that Microsoft’s key issue with the PS4 Pro is the fact that it doesn’t feature a 4K Blu-ray player, an unusual omission indeed.

What’s more, Aaron Greenberg, Xbox Games marketing boss, tweeted a list of specifications for the PS4 Pro before proclaiming that Project Scorpio – the codename for Microsoft’s speedier Xbox One that’s currently in development – will be the most powerful console ever made.

Microsoft says Project Scorpio will have six teraflops of processing power compared to just 4.2 teraflops from the PS4 Pro.

Pure processing power is one thing but Sony potentially has something even more powerful on its side – time. The last we heard, Project Scorpio wouldn’t be ready until the 2017 holiday shopping season. Sony’s PS4 Pro, meanwhile, launches in two months on November 10 (priced at $399).

Assuming both launch dates stand, Sony could have a full year on the market before its next next-gen competition arrives.
