We have a had a long delay due to active Trident development. Now that we're back to Dolphin this should be a normal pace. Release date isn't set yet, but we have a rather small list of things that we plan to do before the first beta, so not too long now. Your suggestion about splitting the updates is perfectly relevant - we had a much larger TODO list initially and separated it into 3 consecutive releases (7.2 - 7.3 - 7.4).
