How can you say for certain it WILL?
Nothing is certain until we have more information.
What information we DO have is that trading is limited to items below the top tier. Granted, it's been a long time since they talked about trading - but when they did, they made it a point to say you cannot trade the best items, you have to find them yourself.
So while they could have changed things in who knows what way, all the information we ACTUALLY have (outdated as it is) says it's not p2w.
Until we have more information, anything else is pure conjecture.
