It may be a good sign for all VSC to TSC (resend)

I just check my status this morning, even there is no update information for my I-485, but the date was changed to 6/15/07 from 3/15/07. I guess I may hear something from TSC soon or at least uscis in working on my case.If I am lucky enough, I may be informed the result next Moday, as I saw the same change for my visa application.
My case: PD March 6, 2005. NIW, 1st FP: Aug. 30, 2005. 2nd FP: May 5, 2007. VSC to TSc on March 6, 2007. Update on March 15, indicating the case transfered, since then, sleep for ever untill today.
