Yeah I wouldn't doubt this was more or less a last minute cash in of sorts. Also, it makes sense that they want people to keep buying these games via virtual console on the Wii, and future 3DS and future Wii 2, ect. Who knows maybe they'll spend some time on these games in the future. I just think of the missed opportunities that could have been added. Online leader boards, speed runs ect. The handheld games atleast got some love. Super Mario Bros Deluxe for the GBC is a good example, that game was great, they added point challenges, red coin challenges, hidden yoshi eggs in every SMB1 level. Super Mario Bros 3 GBA version added extra levels, SMB 2 and SMW items, ect.. (all through the e-reader). So I know these versions and extras exist somewhere at Nintendo.
How about a bunch of unlockable art, example would be what is in the Metriod games for Gamecube/Wii also GBA Metriod games. How about just a nice graphical update or a toggle mode between old graphics and new graphics like what they did with TNMT Arcade on X-Box live.
Maybe they should have passed this project onto someone like HAL and they could have game it the Super Smash Bros treatment and really put some love and care into Nintendo's most beloved games. Hmm... well maybe someday we'll see this stuff... I guess that's enough ranting for one post.
