ZDNet has This article that rehashes the fact that Springboard modules are trickling out right now. Many of the delays have been attributed to the earthquake in Taiwan and other component issues.
Yes this has been said before. Yes it is a problem, but I think that by July many of the delayed modules will have been released or will be out shortly. Once we have some of the hyped modules (GPS, MP3, Wireless) nobody will remember the trickle of Springboard modules that we have right now.
