Eh ... so this means no cute TO18 parts to use in super-duper-pimpedup next-gen fuzzface clones with a slight retro slant?

I wonder what happened to the TI opamp parts that were announced a while back.

There are discrete heterojunction bipolar parts out there, although they tend to be optimized for RF use.
