I'm still using Spanning Sync to sync my local calendars to Google. Calendaring is the main sync issue for me: my phone syncs with my local iCal, and then my local iCal syncs to multiple calendars that I have. This is still a bit tricky, since I have a personal Gmail account as well as multiple Google Apps for Domains accounts. My main request is to support multiple accounts and use the "native" login for that account, rather than having to use one account that has access to all calendars. This does work for calendars, but doesn't work for contacts: your contacts will be synced to only one account.
For calendars only, if you have a Series 60 phone, there is also CalSyncS60. This lets you sync directly from your phone to Google calendar. Except, I never got it to work quite right, and I don't have a data plan at the moment, so syncing would be mainly at the home or office where I have wifi.
I didn't watch the video today, but did scroll through the MacRumors live update. Looking through the transcript and poking around the various updated pages at Apple.com, there are some interesting tidbits that I think I can extract.
Here as well are some other posts that I found interesting:
