I believe it to be the nature of many programmers to see that as more of a challenge than a clear cut impossibility. Very few games are released with official tools, and although naturally it's on the rise because of the foreseeable advantages of it extending a products lifecycle, many dedicated and talented individuals put the time into reverse engineering many formats and packs in order to develop tools for the community.

You can already see this happening in the MTW2 community, if it wasn't for the announcement of the official unpacker, a third-party compatible unpacker would still be underdevelopment. It's good to see CA have already acknowledged this but decided to directly support the community by releasing official tools for their game, as well as their optimistic view on providing additional, more advanced support for modders in the future. :)

Secondly, I'am going to wait until a few people actually manage to get their hands on the model files from the packs and experiment before passing judgement on how supposedly 'complicated' the format is.
