Ummm no.

The pronto can handle as many devices as you can fit into its memory. There are no limitations on devices or types of devices. Just an overall memory limitation. Just for your info, my CCF(pronto config file) is 227KB and it is one of the larger ones out there. I don't have as many components as you but I have a lot of redundancy and BMP's. My device list contains 25 items totalling 76! panels. My pronto has 27% of its memory free.

You shouldn't have a problem.
