I just want PLCC packaging and 5 volt logic. I keep looking at all the 
new FPGA logic
thinking that would be a nice chip and I don't like the packaging or 
voltage.Also with all
the new chips you get more pins, but more of them are power.

Also all my designs are nice and slow LS speeds.That is not to say I may 
not go faster
but right now slow I/O devices are the factor for me.
PS. BG. Micro also has some nice heat sinks just in case you need them 
for a linear power
supply,
