(What/could) hardware revision for the Wii (will) increase it sales?

[dunno001]

Call me weird, but I could see a significant hardware revision helping. No, HD is not needed, but perhaps more internal storage space, and the ability to run stuff directly from the SD card could help both system sales and the online store sales. Slimming it down would also be nice, but that may have to come at the cost of GC support...
