No TwiTrinity at MTV Movie Awards This Year?

The TwiTrinity presenting The Twilight Saga:  New Moon's exclusive clip last year. 

This is the word for now.  So sad if its true.  MTV Movie Awards 2010  will air on June 6 at 9 p.m. EST.

Two days before the release of her new album “Bionic,” Christina Aguil­era will be pre­view­ing some tunes at the2010 MTV Movie Awards. The pop singer so far is the only musi­cal per­for­mance announced, while Aziz Ansari has been crowned host of the Los Angeles-based ceremony.

On tap as pre­sen­ters are Tom Cruise, Cameron Diaz, Zac Efron, Jonah Hill, Jes­sica Biel, Bradley Cooper, Steve Carell, Miranda Cos­grove, Shaun White, Vanessa Hud­gens, Sean “Diddy” Combs and MTV favorite Rus­sell Brand. Absent from the list are the stars of “Twi­light” – Robert Pat­tin­son, Kris­ten Stew­art, Tay­lor Laut­ner — whose pres­ence dom­i­nated the broad­cast (and the win­ners list) last year

So they are not in the presenters' list at this time.  Does that mean they are still attending?
But it woudn't make any sense if they will be there and not present their summer hit movie, Eclipse, right?  Let's just hope this list is not final yet.
