I have no idea how reliable this channel is or if anyone actually caught this on the blog before it was removed (if it was there at all). Apparently in the post it read:
Take your Playstation gaming to the next level with Playstation Infinite. All existing PS+ and PS Now subscriptions will convert to Playstation Infinite Gold for the remainder of your active subscription.
If this is true, that would imply the base tier will include streaming which is different from what the leaks have said, iirc.
