What is the transaction throughput capacity of BCH vs BTC?

I've heard the yearly transaction maximum for the Bitcoin network (BTC) is 200 million transactions a year at max. Is this correct?

What is the upper limit for BCH? What about something like LTC?

What are some comparable figures for the Visa network?

P.S. Let's try not turn this into an emotionally-loaded discussion rehashing the blocksize wars. If responses could be kept strictly on the facts I'd appreciate it.
