Don't forget that TakaraTOMY have wanted to do the Toyota Hilux MP for years now. It was mentioned in a magazine interview ages ago.
Also, I don't think any evidence has emerged of Porsche having agreed to grant licence for TFs, so it's possible that the MP Cliffjumper prototype was made, but they're awaiting Porsche to come to the table before proceeding. Don't forget that Takara also made a prototype for a Porsche Binaltech Meister, but Porsche refused to grant licence, so the toy ended up being a Mazda RX-8 instead.
