PayPal, from my understanding, is a weird situation. Do I think it will come "soon" (as in next month or two), no.
But if I recall correctly, at one point, someone said they were thinking of bringing in another provider (besides Stripe) for the Kick's (bits) integration. So if it's coming, it'll likely be around then.
For Wizebot, that's dependent on Wizebot. They could integrate now, that's how Botrix, AeroKick, BeepBot and others are working (public API). Or they can wait until the official API release, then it's open season for everyone.
