Drake just seems very much like one they would make too. Much to Jester's frustration I think NECA will front the squad with first the main marines as they have already done (Hicks, Hudson, Vasquez) and second the more distinctive looking marines (who also happen to have more lines) - Drake, Frost, Apone if they are possible. The Gormans, Crowes, Dietrich, Wierzbowski's, Ferros and Spunkmeyers will be last on their priority list.
My worry though is that a strategy like that might mean those lower priority characters just never happen based on the principle that lower-seller characters would want to be mixed in with higher-seller characters to assist in sales. A bunch of low-sellers at the back end of the line might see them tank at retail.
