Well wiiware was in its infancy and so far there are many people downloading wiiware games already so what seem to be the problem?
What wiiware developers must do now was be patient on what Ninty will do next. I know Ninty only testing the waters here before they heavily advertised it, and theres still the storage solution Ninty is working on, so wiiware developers shouldnt rush on these.
end of core gaming days prediction:
E3 2006-The beginning of the end. Wii introduced
E3 2008- Armageddon. Wii motion plus introduced. Wii Music. Reggie says Animal crossing was a core game. Massive disappointment. many Wii core gamers selling their Wii.
E3 2010- Tape runs out
