i-Pod connection & digital radio
bigger sunvisors; the current ones are useless
touch screen for PCM with sensible drop down menus. Adopting touch screen should enable a larger display size, because the buttons on either side of the display can be eliminated. Also, navigating through menus and entering information would be a doddle - much quicker than scrolling back and forth with the frustrating little wheel. Also useful with touch screen would be a feature that allows you to drag the map around with your finger, kind of like you can with your cursor on google maps. Often I like to see part of the map that is just beyond what is currently being displayed and there is no simple way of doing this unless you zoom out, but then you lose all the detail. Please whatever they do, do not go down the i-Drive route that BMW and MB have taken.
a feature on the radio that would automatically reduce the sound volume when white noise is detected. For example, if you are listening to the radio and then drive into a tunnel or other area with no reception, it would be nice if the radio automatically lowered the volume instead of playing the no reception hissing sound at high volume.
20% larger fuel tank
smaller exterior dimensions, maybe something inbetween the old aircooled size and the current size
more power less weight [

smoother gear change on manual cars
the key looks and feels very cheap - so much for sense of occasion..
don't eliminate the sport suspension + LSD option
X51 power kit as standard
Better looking / more exciting exteriors. The designs are starting to look a little bit bland. The current 997 is fine at the moment, but the current cayman/boxster range and the facelift 997 (from what I have seen spy shots) all look horribly bland from the front. Even the Turbo looks a bit unresolved from this angle.
Apart from that, keep up the excellent work (eg performance, reliability, handling, driveability, brakes, low end grunt, reasonable fuel consumption & emissions, safety, comfort, etc)
