That's what I'm thinking.. Gaara's death was too..simple. It lacked a very emotional music score or something..it felt so empty.
When I heard Chiyo say that she sealed Shukaku in Gaara, I just knew that she would do it again, and die in the process. Maybe she'll use the same kind of sealing jutsu as the 4th Hokage used to seal Kyuubi in Naruto.
It didn't make sense when Chiyo said that she sealed Shukaku into Gaara, since the method the 4th used on Naruto killed him, so I guess there are multiple ways of sealing a Bijuu into a person....or it's just a very deep plothole..
Gaara is just too cool to die.. he just..can't...
