Still though, if I had a V3, I would not get the 722. I would get the PMD-671
I recall that the 671 is larger than the 722, which could make the difference in a stealth situation.
I could not find battery capacity information for the 671, but the 722 will run about 4 hours without a battery swap. That was an advantage over the other devices I considered while I was impatient for SD to release the product.
Also, I have an 80G drive in my 722. None of the CF-only devices will ever keep up with the 722 storage capacity. I realize that seems like a mute point once CF capacities hit 8 gig. But imagine going on tour with a recorder that never needs to be emptied until tour is done. For someone really worried about vibration, there are HD form factor high density solid state drives that will fit in the 722 drive bay, but they are hella pricey. By the time 8G CF cards are cheap, there will be 240G drives for the 722. Thats all of tour and the openers at 24/96.
These are just some other data points to consider. I haven't run my V3 since I got the 722 but I'm holding on to it until I have more time with the 722. If I like V3 better, I will use it for open taping situations. The 671 looks like a sweet box. I guess it remains to be heard if the 671 front end is competative with the 722.
If smaller size and higher stoarge capacity isn't a requirement, the 671 looks like it will be in the section a lot this summer.
