VGA would be quite nice
The SoC doesn't have native VGA, so this would take additional circuitry (read: costs money) as well as finding somewhere to stick the connector.
There are, basically, two ways to get this. One would require picking another SoC--which would mean a whole new board design. The other would require someone being willing to die-shrink the SoC. Either way, you're talking up-front money....potentially a whole lot of it.
Personally, I think more performance will happen, but the board will likely not be called a "Raspberry Pi". I don't think it will happen particularly soon, either. I'd look for it in 3 to 5 years.
Optional full-feature power supply module containing:
AC-rectifier, protection for over-voltage, over-current.
Multiple input: PoE, USB, DC-barrel, PP3 - with hot-swap.
Power switch, DC-DC up/down (3v-30v?) switch-mode regulator, big capacitor.
low-voltage / brown-out warning signal by GPIO flag (or analogue input from source).
wake-on-LAN, wake-on-modem, wake-on-GPIO
Full power-off initiated from software or by built-in shutdown button.
This sort of thing is what I'd look to third parties for. Adafruit, for instance. A (relatively) long time ago I suggested something like this to include regulated power, a powered USB hub, and (as an option) an HDMI to VGA converter, all done in the same footprint as the Pi, permitting a "stacked" case to hold both boards.
