User blog comment:Aleksandr the Great/Prothean Squadmate is Officially DLC/@comment-919588-20120222154148/@comment-1655340-20120222172926

I agree with you Lightna. Yes, it does suck that the character was not included with the game proper, but honestly, how many of you will get him with the CE, and how many without it are gonna buy him for $10 (and however much the charge would be for other countries)?

The Prothean will be no doubt an awesome squadmate, and if he's in the game already (and, as a user pointed at, this would merely allow us to recruit him to our party), then I hope that other characters follow suit, which means we could get characters like Conrad Verner, Aria, Patriarch, Kolyat, Shiala, etc. as future DLC squadmates.

Since the story is meant to be the last in Shepard's trilogy, other than James I doubt they'd bring in any new out-of-the-blue characters as squaddies.
