Which "market" are you referring to? (Where do you live?) For some companies like Ibanez, specific model availability varies from region to region.
There aren't too many production 7s available in the North American market these days, but there's still some choice.
Ibanez has the K7, RG1527 and AX7221.
Carvin has the DC727 and DC747.
Schecter still has a couple of models available... the Omen 7 and 007 Elite.
ESP has culled all the 7s from their LTD line, but has introduced a really nice new Stephen Carpenter signature 7.
