Latency is one of the problems with regards to creating an economy of scale and centralization. It may actually work better to increase the block size by having 3MB blocks with 20 minute intervals or 1 hour blocks with 20MB caps, though that also has some centralizing pressures in increasing the full node expenses and may even result in latency-blocktime ratio increasing. There also is of course the problem of confirmations being inconvenient with 1 hour blocks.
