I think that Olympus may reduce the number of 4/3 dSLR's in their offering but I believe that they'll over [sic] a compact, mid-size, and high-end one nonetheless...
I'm sure that if people continue to buy 4/3 DSLRs in significant numbers, Olympus will continue to make them. However, I think that the number of u4/3 cameras flying off the shelves, in addition to Sony, Samsung, and others making moves to break into the burgeoning market, provides little incentive for Olympus (or Panasonic) to continue making 4/3 DSLRs. As for the diversity of u4/3 cameras, Olympus is already trying to fill in the low-end with the E-PL1 (only $100 more than your E-420, which came out 2 years ago), and Panasonic already has a high-end offering in the GH1.
Olympus isn't a Nikon or Canon in terms of its size or footprint in the camera market (especially with professionals), so it has less room to experiment with different models. I predict that they'll go with the winner of the two formats, and gradually phase out the other. Panasonic has no huge stake in the camera market, but when you compare the rate that 4/3 DSLRs have been released by them over the years (2 in the past 4, with the last one in 2007) to the number of u4/3 cameras that they've released lately (3 in the past year and a half), I think it should be clear which horse they're betting on.
I think this is great! Who doesn't want a camera that can't frame a shot in bright sunlight? Composition is so overrated.
I know you're joking, but apparently a
lot of people want cameras that can't frame a shot in bright sunlight. Why do you think they stopped putting viewfinders in compacts?
I'm fairly certain that the average person's idea of good composition is putting the subject smack in the middle of the frame. These are the same people who use their onboard flash when taking photos from the nosebleed section at concerts and sporting events.
