I’m very doubtful of this. Doesn’t match with what leakers have been saying recently about MS being willing to sell Xbox Series at a loss. It also doesn’t match with what other leakers have been saying about MS delaying their Lockhart reveal and pricing announcement out of August because they want to wait on Sony to announce price first so that they can undercut them with both Series S and Series X. $550 or $600 not only wouldn’t be a loss, it would be a profit for them, since the bill of materials is reportedly in the $460-510 range. I just can’t see this happening. $500 tops with a good chance of $450 imo.
Im very doubtful we would see a 450 price point. I think 500 is the sweet spot and I think gamers will accept it well as they know the power inside. For me 600 would also be ok but I understand most people would be against it. But I really cant see it below 500. As for sony I think the discless version might be 450.
