I'm not that worried, its normal to not get many promo pics (or spoilers) that include Greg. I thought last season was awesome as far as screen time went. I'm gonna wait and see - and hope for the best.
Now that Sara is back (rumor has it shes back for good but I hope not) maybe we will see a lot of Greg working with Sara again. Although I personally prefer him with Nick.
