lexus LF-A, which is touted as the new supra
The 'AE86' is the hatch thats being codeveloped with subaru and toyota, not sure what the latest progress on either is. Haven't heard many noises about this lately
LF-A was supposedly canned/on hold late last year/early this year due to the economic climate.
edit:
There is also the FT-HS that was going to be the new supra as well, actually that might be the co-built one with subaru
