I get the impression that some are confusing [Title] 2.0, which denotes a major patch/upgrade to a computer program (or, for instance, George Lucas' frequent tweakings of the Star Wars movies), with [Title] 2, which denotes a sequel -- a different story which continues the same characters and overall situation from a previous release (e.g., the Final Fantasy series, or the individual Star Wars movies). I'm certainly having trouble keeping track of which one is being referred to by any given message here. :/ The first is a revision of the same release; the second is a whole separate release.
So, APR might be CoH 1, version 2.0 -- still the same game, but improved.
