It is unclear how MS proposed XPlay is like.
If MS insists all XPlay must be connected to MS server only, it will be bad for Sony if they refuse it after agreeing.

That is already proven that they doesnt mind crossplay with other platforms.
Really clever of MS to deliver this "inconsistency" of them into their favour.
