I don't think they have ever had a bundle including multiple platforms. Sounds like you prefer the PC. Maybe buy PC first and then buy the PS4 when it goes on sale. The best place to ask these kinds of questions may be support chat. If you hit "contact us" you will have to do at least one search and then they give you the chat option.
