I'm sure current M8 owners will feel differently, but I think a steep drop in M8 prices would be a good thing for
Leica itself in the long term.
The reason is that if we look at the
set of serious photographers who currently "get" the whole rangefinder thing, and the
set of serious photographers who can afford to drop $7,000 on a limited-use camera... well, the intersection of those sets has to be a fairly small number.
I suspect most of those fortunate few have ordered their M9s already.
So if Leica wants to keep M9 sales going beyond the initial feeding frenzy, they have to find a way to make the M9 relevant to serious photographers who don't use one already. In other words, they need recruit more "rangefinder fanboys" (I can use this term without insult because I'm one of 'em) on an ongoing basis.
Unlike, say, celebrity shooters (Seal,
John Sandford) who might value a prestige camera as a take-me-seriously merit badge, hardcore photographers care about only one thing: "Will this kind of camera improve my chances of making the pictures I'm driven to make?" If it costs $7,000 (plus the cost of lenses)
even to start to find out the answer to this question, Leica is going to have a hard time recruiting candidates to roll the dice.
It was different when M8 first appeared, because then there already was a lower-cost "entry level" DRF camera: the Epson R-D 1. Yes, it had some initial quality problems, and no, it still wasn't exactly cheap (although it eventually became almost a hot seller as a $1995 refurb) but it certainly offered a much lower-priced point of entry to digital shooters who wanted to give the "rangefinder aesthetic" a try.
Of those who tried that shooting style and liked it, I suspect many eventually graduated to Leica bodies. However, with Epson out of the US market and no other manufacturer willing to stick its hand into the meat grinder, Leica no longer can rely on a competitor to furnish a lower-priced "starter" DRF. The only answer is for the M8 to fill that role.
Incidentally, I feel that when it comes to recruiting potential rangefinder fanboys, the X1 is totally irrelevant to this discussion because (a) it's not a rangefinder camera and (b) it doesn't have interchangeable lenses.
In other words, it might seem like an alternative to Leica fans who want "another Leica." But it's not going to seem that way to brand-agnostic photographers who only care about taking pictures.
They wouldn't shop the X1 against the M8/M9... they'd shop it against other fixed-lens "serious compact" cameras such as the Sigma DP2 and Ricoh GRD III, or (going up a notch in size) against the pancake-lens versions of the Olympus EP1 and Panasonic GF1.
