Is an FPGA the Best Option for High I/O (120-150 Input) Prototype?

Hi All, I would like to give some context of my project first before asking the question so you can understand where I am currently at. context I am starting to create a prototype of ...

If it's a distributed system as Dave mentioned, yes probably microcontrollers are the way to go.

Otherwise, your favorite microcontroller and a CPLD for the I/O expansion will work very well together. An FPGA (with possibly a processor, and possibly external memories) sounds like overkill.

Regarding an "overly messy processing loop with a microcontroller based design", if you are more specific others can comment on how programmable logic can/can't help you out.
