Seems the end of that deal with Ferrari just meant the end of exclusivity to the HW brand but not the end of Hot Wheels offering Ferraris, because some of the 2015 cars are for sale on eBay, and the 599 GTB Fiorano is one of the cars in the 2015 lineup, and it looks awesome.
Can't wait to see what else the 2015 lineup will include, but it's great to see these cars returning!
Edit: I just found a post on The Lamley Group that mentions a couple more 2015 models, along with showing more of the final 2014 batch cars, many of these likely have already sold out, as I can't find them on eBay.
The Aston Martin DB5 is also back for 2015, now in a nice shade of red.
The green Datsun 620 that everyone knows about by now, plus on card looks at the 934 Turbo RSR and '15 Ford Mustang GT.
