It's looking like they will pack the remote, the analogue stick, AND the shell with the console. I don't mind at all if it raises the price a bit - in fact, if it were too cheap average consumers would feel like it was missing something (like the Cube, even though it was more powerful than the PS2). The console, the attachments, and Mario 128 or SSB:R bundled in for a MSRP of $259.99 US. Perfect.
I definitely agree that the new controller should be pushed more than the shell, but it deserves mention, if only to appease the doubters.
And they could advertise all of the attachments with the controller. First, a quick 360 degree (lol) view of it. Then, footage of the ORIGINAL Super Mario Bros, with the person playing with the controller tilted. Then, that footage fades/blends into Mario on the SNES. After that, it becomes SM64 then SMS, but NOW with the player playing with the shell. And finally all new footage of Mario 128, using the remote and portraying the tilt function. This advertises the controller w/ attachments, AS WELL as the download service (it could be mentioned).
I hope that the remote is re-designed to seem more comfortable and non-angular. Some curves here and there to make it fit perfectly in your hand (like the GCN controller) whichever way you hold it would go a long way. The analogue stick attachment looks more like it.
Finally, I think that the shell should be like the Gamecube controller but with two analogue sticks.
The button layout; a large A button, a kidney shaped B button directly to the left (not angled), a left C button (except quite a bit bigger) right above the A button, a [down] C button directly to the right of the A button, and a right C button on the far corner, opposite the left C button. The Z button should be redesigned to be made easier to click and more comfortable.
This way, for 64 games, you have the normal layout, but there are 5 face buttons and for the up C button you could use the new Z button
