It was probably ignored because of the PS3 version. Now that they'll get ME1 too, we can (zhu's...) hope...but I don't think it's going to happen, after all, even on PS3, we didn't know that Shiala even existed, so they could have just as well made her pop in the DLC without people thinking "hey, I killed her !", but they didn't. I still like the idea though.
And sure, Shiala is yet another asari, but it's one of the few characters we've met who would be a credible squadmate. Though if Aria is a temp squadmate in the Omega DLC, there's no way we'll get another DLC with Shiala (but I wouldn't mind... everyone likes Asaris

)
