If you don't want the stuff they are releasing, DON'T BUY EM. Some other guys might like the old reissues(me for instance), and will buy them.
It's too bad that AMT and MPC doesn't form their product line around what you want, but if what you want is more 32 Fords, rather than a 65 Rivera or a 57 Chevy gasser, then I'm glad they don't.
