has a teaser video. There's not much in it...
Some of the discontinued Nissans were discontinued/replaced ages ago. 300ZX was killed (became too expensive) and there was no Z car for while until the '03 350Z. 350Z became 370Z due to change from 3.5 to 3.7 liter V6.
IIRC, Altima Hybrid ended after '11 model year. '12 model year also marked when Camry Hybrid went to a newer gen of hybrid system. As far as I can tell, Altima Hybrid (my mom has had one for years) uses Toyota HyCam hybrid bits, including inverter, power split device and batery pack. So, probably Toyota and its suppliers didn't want to continue supplying large quantities of previous gen hybrid bits.
Some of the cars from https://www.cars.com/research/nissan/
are pretty funny. Stanza went away in the US long ago.
