Reliability
I'm going to be a little more realisitic.
The iBooks won't get a 64mb graphics card, they will just be slightly improved, they also will be out in the latter not quite as soon as some are hoping. The powerbooks all run a 64 mb gpu it ain't happening to the ibooks this time. They should really update the iBooks without worrying too much about the crossover of the Powerbooks, as the Powerbooks do have other features. And they in turn will also get there updates in following months. They really should make the iBook 64mb Gpu.
HD imac I don't know. maybe. Updated GPU's to 128mb at the two top models definately. And the option for a higher type of card.
As for the pro mouse. 2 button, no. They have spent there entire life developing progrmas around this, trying there best to make things more user friendly, this is what they stand for, not giving up and taking the easy route. But a Mouse with a touch like scroll, definately. Its overdue.
I think the main reason for any of these updates (except the iBook) should be to improve reliability. The iMacs have many flaws (the fans, motherboards, psu's etc etc) The powerbooks have trackpad problems, and there isn't even an update. The Monitors (Aluminium) have many colour problems, although I haven't witnessed them in person. The pictures I have seen online do show those yellow stripes, blue stripes and pink patches, but from what I can see they aren't all that bad. But there is still many people complaining, and they have a right to. They are buying the most expensive montiors on the market and from the best recognised brands in graphics computing. I don't know about the powermacs, but there were many psu problems with them earlier, If Im not wrong they are still on going.
IMO all of these issuess should be taken care off immediately. If they choose to throw in some upgrades while doing this then let that be, JUST MAKE SURE THEY WORK PROPERLY. Apple, in order to stay alive are taking as many shortcuts as they can. They are using cheaper manufacturing methods or the testing labs have experienced a cut in funds. Whatever it is SORT IT OUT STEVE!!!
