Give the "no-name" games a chance, you never know, you might find something you might like. I'd never heard of Bonk's Adventure until it came out on VC, but I'm glad I downloaded it because it's top notch.
Ultimately Nintendo are never going to satisfy everyone. What you might consider another dull week might be exactly what I always wanted, or vice versa. I do agree they should at least give us release dates though, it's rather annoying just seeing a release date of "2007" for a game which could be out tomorrow or not for months.
