Wii Memory Upgrade. Nintendo is currently working on one and at their Nintendo Press Event they stated that as of 2009 games were going to be able to be saved to SD Cards. That is not satisfying for the following reasons...
1. They Are Small and can get lost.
2. They Can be lost and/or destroyed
I love Nintendo, but what they should do is a memory upgrade. Here are the details here..
1. A extremely massive memory upgrade, that can be purchased or downloaded.
2. A gigabyte memory upgrade (5 to 10 gigabytes)
3. Also comes with a system upgrade.
This is what the upgrade should be. This in my opinion would allow for games like Red Steel 2 and several other titles to have DLC, and I know how much the gaming community loves DLC.

All the Zero games are gathered into one DS cartridge. Elder-Geek.com loved it in their review.
Elder-Geek: Recently, there has been a resurgence of Mega Man love and I, for one, couldn’t be happier. Those who know me would say I might be a tad obsessed with the series but I say a Mega Man themed wedding is perfectly normal. That aside, my respect for the franchise has been dragged through the mud with its numerous useless incarnations, like Star Force and, to a lesser extent, ZX. Even the retro MM9 and MM10 had me severely disappointed and wanting more. Mega Man Zero, however, is a testament to the great things that can be done with the franchise while keeping true to the series roots and with all four games wrapped neatly together into one edible cartridge, there has never been a better time to give these spinoffs a try.
SCS Software released a large chunk of gameplay of the upcoming Illinois DLC for American Truck Simulator, focusing on Chicago.

MINOS lets you construct your own perfect Heath Robinson/Rube Goldberg murder machine.
You know, with the amount of useless peripherals Nintendo has put to market, i'm so surprised they haven't swallowed their pride and admitted we were wrong "our customers want a storage device" The SD card isn't the way to go, furthermore SD card's have a higher corruption ratio than hard drives. It's unbelievable that the masses amount of content available on the Virtual Console & Wiiware that Nintendo decide to work and create the DSi and have more attention towards that than potentially making shed loads of money on its own official hard drive and the ability to offer DLC. It's pretty shambolic its another stab in the back to the serious gamer by Nintendo.
