confusion

i am little confused about the new love story offered to shaheer.
one article says that its nothing but 'teri meri love stories'
another says (metromasti) thats its some other love story & not 'teri meri
love stories'. which exactly is true. in teri meri love stories promo shaheer is
not shown. but it could be to mislead bcos even when they first showed
'diya aur baati hum' promo, they showed some other actors but later they started
showing promos which showed the actual actors who r now playing the lead role.
what is the truth? can somebody enlighten me

actually all that were promos and there would be diffrent stories so once it will started they start showing original actors...
