They never said part 3 is going to be on all platforms day 1. They just said they're putting them on other platforms which... they've always done. Remake dropped on PC a year later. This deluded idea that you think putting it on Xbox will results in millions of sales is pathetic. As if they waited 5 1/2 years to drop FFVII Remake on Xbox because "console exclusivity wasn't cutting it."

The bullshyt you tell yourself on here is just funny.
Xbox install base is
simply not where JRPGs are mostly played. You never thought the idea that Sony probably didn't need to keep paying for exclusivity for FF since Xbox is practically inconsequential? You and Meach really sitting there thinking Rebirth and XVI sold like garbage on PS5 and Square was like "Damn damn damn we need to release this shyt on Xbox!

"
Multiplatform is mostly talking about Steam/Switch 2 and still that wasn't confirmed to be releasing there day 1 yet.
