So no mention of release date. What good is this information other than to stifle sales of the D4?
It's a lot of information. "No new sensor", is the first thing I read in the announcement. Nothing about "high res".
So it will be the same old 16MP D4 sensor , probably in the "improved" Df version. No increase in fps. Slightly tweaked AF algortihms (no new AF module). Slightly improved new "X peed" chip. Somewhat better video. Maybe, just maybe WiFi built in. Yawn.
Instead of a kick-butt D4x based on the 36MP D800/E sensor plus revolutionary new dual-pixel AF.
WiFi, NFC, GPS and radio wireless flash commander built-in. Along with 2 matching radio-controlled CLS/iTTL speedlites and transceivers for existing older speedlites, instead of continued stone-age optical triggering.
