Lens price fixing? No package deals to be had anywhere!

It actually is price-fixing (a form of vertical price-fixing called resale price maintenance).  In 2007 the U.S. Supreme Court ruled (in a 5-4 vote down party lines) that these minimum advertised pricing restraints are not per se illegal under antitrust law, and so the use of these has become ubiquitous.  Now every camera manufacturer controls the minimum price at which retailers can sell camera gear.  As a result prices in the U.S. for camera gear are much higher than in Asia, despite the huge devaluation of the yen and the lack of any value-added taxes as in Europe.

However, the SC opinion was in the context of a single boutique leather apparel company wanting to control its prices in a sea of competitors, not an entire industry of conglomerates (Canon/Nikon/Sony/Olympus/Panasonic/Fuji/Ricoh/Samsung) all fixing prices.  One of the dangers the SC majority opinion acknowledged if an entire industry uses vertical price-fixing, is that it can become a horizontal price-fixing scheme (e.g. a manufacturer cartel).

Olympus USA would have you believe you're getting a bargain on the E-M1 because it's $100 off ($1200) and the 12-40 PRO is $200 off ($800).  But contrast that in Japan - as an American tourist you can walk into a big camera store in Tokyo or Osaka (Yodobashi/Bic Camera) today with your passport and Visa card, and get the E-M1/12-40 PRO for under $1300 USD with a multi-year Japanese warranty.  You're essentially paying a 50% premium largely due to these policies.
