I just got back from being off-grid for 10 days and I see the release/pre-orders and I almost ordered the Z-7, had it in the shopping cart!
It's way more resolution than I need or could really use, but having more AF points and no AA filter makes it more appealing to me... plus the other benefits that such high resolution offers is enough for me to accept the file sizes and slightly slower frame rate. I can live with a single XQD card for my use... I've never had one fail in any way (YET). BUT, the drop to 5.5fps to have AF/AE active is a no-go for me, such a shame.
Looks like I'm still waiting for the yet to be announced (and more expensive) professional model.
