Still sticking with a $500 discless ps6 and $550 disc ps6 bundle at worst with the disc drive being $80-120 sold separately. Sony are going to pay attention to the sales rate after the price bump this year and especially next year to see whether or not this can be the standard next gen. With sales rate being the same or better, Sony are definitely pricing at the stated prices above as the new standard even after the tariffs are over, possibly prioritizing the $500 version.
The ps5 pro is not selling well, with a worse sales rate than the ps4 pro. With the new price bump, the sales rate will decrease. A $800-900 ps6 pro with no disc drive will definitely not sell well since a ps6 pro would probably be at those prices to provide noticeable upgrades over the ps6 so I believe there won't be a ps6 pro next gen. Sony are going to go all out with upscaling and possibly frame gen next generation with better graphics, better ray tracing, and path tracing. A ps6 pro won't be appealing when the ps6 can provide quality setting graphics with raytracing and path tracing at 4k and 60-120fps using upscaling or dynamic 4k and possibly frame gen.
