Well the e-P2 with kit lens is $7849.99......9-18mm is $599.99 the latter is $130.00 less than listed!What does a 'drastic reduction' mean to you? Like 70% reduction? Could just be a local event (i.e. single shop trying to clear out some inventory). Not sure you can necessarily generalize that to a global market. There are some new lenses rumored to come out, and there are discounts on a number of lenses going on all the time as the market saturates, but nothing I'd call 'drastic'.
I get the feeling the m4/3 market is becoming saturated a bit, and I'm not sure if we'll see a large influx on new customers unless there's some dramatic new product coming out in this format.
