I've been so pleased with my X100 and X10 that as soon as I could, I pre-ordered an X-Pro1, the 3 lenses, and a spare battery, at Henrys in Toronto. I was only #11 on their waiting list.
But by yesterday, I had seen enough of the E-M5 to convince me it would suit my needs at 1/3 the price. Anyway, I've always preferred SLRs (I have several Exaktas, a Praktica 6x6, and 2 worn OMs). And the OM-D can use my old E-PL2's lenses, adapters, etc. - even my VF2 viewfinder if I want (unlikely but technically possible). So I phoned Henrys this morning and cancelled the X-Pro1 even before today's announcement.
Now that dealers like B&H, Adorama and Amazon are taking orders, I'll call Henrys tomorrow and pre-order an E-M5 + 12-50mm lens. A black one.
I still want an X-Pro1 someday, but for now I'm saving enough to pay for this new Oly pro-style camera and a 3 week Summer trip to Southeast Asia, a dream vacation my wife has been pushing for.
For once, common sense has trumped my newer-better-gotta-have-it gear lust. It hasn't done my marriage any harm either. 😀
