Open mouth, insert foot...
Cute.
In any case, as firestarter said, it's unlikely that Olympus would choose to alienate their (evidently rabidly loyal) existing customers by discontinuing 4/3 DSLRs immediately.
Once again, as I said, this is all dependent on how well 4/3 DSLRs continue to sell. Olympus and Panasonic were the only two companies to adopt the 4/3 standard, and as someone astutely pointed out:
Panasonic, on the other hand, has no dSLR's anymore anyways...
...meaning 50% of 4/3 DSLR manufacturers have opted out and moved on to the new format. I'm willing to bet that this had more than a little to do with poor sales of the L1/L10/Digilux 3, and I'll also bet that the GF1 has already outsold them all. Tell me, do you think Panasonic is going to keep making 4/3 DSLRs?
I'll now forgo continuing to ignore (out of courtesy) your blatant fanboyism and say that, as far as Olympus goes, they need to find a compelling reason to continue offering new 4/3 DSLRs and lenses. A 4/3 sensor will always provide inferior image quality to that of a larger sensor, due to the laws of physics. That is to say, 4/3 doesn't offer the same advantages over u4/3 that, say, Nikon FX does over DX. Therefore, since they realize that the laws of physics will endure for the foreseeable future, Olympus and Panasonic decided to play up the strength of the 4/3 sensor (smaller cameras). The advantages of DSLRs (better autofocus, better and built-in viewfinder) will be overcome by EVIL technological advances. when this happens, the only thing a 4/3 camera will provide over a u4/3 one is more bulk.
Until then, Olympus will continue to sell 4/3 DSLRs, even if that entails offering a glut of fairly undifferentiated and (ironically)
largely interchangeable cameras. They're attracting new customers with u4/3, but they can't pull the 4/3 rug from under their old ones, just yet. As the u4/3 line expands, though, I predict that 4/3 development will slow to a halt. (Prove me wrong! Oh, never mind, you can't. Sorry. Wait... Do you own a time machine? Or, are you married to Rachel McAdams?)
Unfortunately, I know that I'm wasting my time and effort, here, because until you're personally forced to toss every single 4/3 DSLR on the planet into an incinerator, you won't be able to even entertain the possibility that 4/3 DSLRs just might potentially be somehow discontinued at some point in the future. Such a reasonable clientele; no wonder Olympus is afraid to take your cameras away.
