<<The key to the time required will depend greatly on discovery time lines.>>
Putting aside each side's incentives in answering the question, my initial reaction as a nonlitigator was that one year is very long, but on further reflection, I'm not sure that is true for even moderately complicated commercial litigation. An elevator conversation with a litigator suggests that one year would be quick for most complex commercial litigation. Obviously the answer depends on how narrow the issues are, how many people need to be deposed, etc. In this case, even if you thought that the liability issue would not require extended discovery, I could imagine a great deal of discovery on various issues relating to damages.
