It sounds more like an on-set drama that was picked up by the tabloids. Halle has always been popular with the tabloids because she is glamorous and looks good on covers in slinky gowns, beachwear, etc. Add a few dramas to that and the tabloids are watching even more closely. Sadly that has overshadowed other aspects of her life and left her open to the same comments directed at most other tabloid fodder like Paris Hilton, Lindsey Lohan, Britney, etc.
At the end of the day, I'm not bothered if Halle or Storm is in the movie. Omitting the character or recasting the future version, or introducing a new young version in the past would all be okay, but they will need some ethnic diversity and a strong female presence from someone. So, if not Storm, then who? Rachel Summers, Phoenix, Binary, Polaris, Scarlet Witch? Any of those would be fine with me.
It would be great to see Storm go up against Sentinels with full-on powers but, for all I know, futureStorm might be portrayed as already dead in the film adaptation.
They might instead use elements of Second Genesis in having Beast, Banshee and Havok captured by whoever is behind the Sentinels in the 1960s, leaving Xavier to recruit a new team (younger versions of Storm, Jean and Cyclops) to rescue them. That would set up a new, young Storm for future films.
Or they might follow the animated series storyline One Man's Worth in which Wolverine and Storm are married in an alternate future - which would require Halle's Storm or (far less likely) a recast.
It could go any of those ways, according to the little we know at the moment.
I'm pretty flexible about it, but they will need some 'girl power' in the movie from somewhere and the actors/characters announced so far don't really fulfil that role.
