"Discontinue" doesn't mean a permanent halt of Ferrari kit production. Tamiya did clarify that.
Hasegawa hasn't renewed their Ferrari license for a while, so I guess it's a similar move.
I'm still gathering more info, especially Fujimi and Revell to see if Tamiya's decision is due to some kind of industry-wide change of Ferrari kit licensing, or just a marketing strategy of Tamiya.
Last batch (at least for now) of Tamiya Ferrari kits should be out this June.
