If PS4 and PC were truly added down the line, then both of those ports would have been completed in under three months which is too optimistic even for the results we are seeing.
That's why I am calling the kickstarter a preorder campaign instead of a normal funding campaign. All ports were nearly complete when the kickstarter went live and they didn't want to take on a big financial risk, so they offered all those tiers to sell a variety of special editions because they knew that the biggest fans would be willing to pay more than standard prices.
Three months is good time for a port to a more powerfull console, easy to program for and with nothing really being upgraded.
