There will be an NBA Playoff game on NBC at 9:00 PM EST.
This means that Dateline will either be pre-empted OR shown at 8:00 PM EST.
According to my TV Guide that I received in the mail yesterday, it is scheduled to come on at 10:00 PM EST.
That would mean that it will be pre-empted.
However, TVGuide.com shows Dateline being scheduled to air at 8:00 PM EST.
That would mean that it would air as scheduled.
So, since Friday's (May 24) Dateline will be the last show until Tuesday (Sunday's is pre-empted) they should announce at the end of the show what will be coming up for Tuesday the 28th.
Let's keep an eye on this.
The only thing definite is that it WILL NOT air at 10:00 PM EST (for all you VCR-heads) on May 28.
My apologies, of course, if someone has already addressed this. :o)
