When they say 1.44 million pixel, they probably mean 800x600 "real"
pixels x 3 (R&G&B).
That's not enough for OVF replacement. Something about 3000x2000
"real"
pixels would be good, but IMO that's going to be years away.

Most people's vision isn't good enough to make use of 6 megapixels of
viewfinder resolution.
With a life size image (say a 50mm lens on a full frame DSLR) you
can't see all the detail that thing is putting through.


.. but you can certainly manage more than the ~400 x ~300 pixels
pushed by some as "high-resolution" replacements for optical finders.


HD video is probably a reasonable standard to strive for.
1920x1080 (less for 2:3 ratio).

It probably is.
How much GPU power is needed to drive 1080 HD at 30 fps with low lag
time? 1920 x 1080 x 30 x 3 x 8 bits is a lot of data. Something that
needs cooling fins isn't going to be much use for a compact battery
powered device.
