Just to throw in a couple cents worth of thoughts.
I won’t be hurt if the 9300 gets a better upgrade card than my 6800U.
I have been using my xps2 for over 6 months now and its still top of the line.
6 months is a long time and the 7800 is not available yet.
If its an easy drop in to the 9300 then there is no reason for dell NOT to offer it so they can be even further ahead of the competition in this little segment.
However, if it requires some R&D to make the 7800 fit into the 9300 then I doubt Dell would do it. They promised it to XPS2 users not to 9300 users. So they are not obligated. Upgraded video cards in laptops is a tiny market. I don’t know the numbers but I would bet that most of the 9300 sales have the X300 graphics card. And those owners don’t care about a new graphics card upgrade. For this reason, since Dell did miss their numbers then spending resources on a tiny market segment does not make sense.
On a different note, if the 7800 does have the standard go6800 power requirements that would mean that I could upgrade my graphics performance and my battery performance at the same. That would be nice.
