HKL has the latest. Good news.
According to Mike Kogan Dynamite!! 2010 will air on TBS in Japan as scheduled, and that TBS is still sponsoring the event. So according to Kogan, everything will happen as planned; TBS will cover a lot of the costs of the event and broadcast the usual stripped down version of the event on television. For those in doubt, TBS has yet to pull the K-1 Dynamite section of their website.
