- Gundam Fix Figuration/Zeonography etc : Highly detailed 1/144 action figure. Obvious difference with others is the appearance of decals all over the body,and usually option parts to change into other mecha
- HCM Pro : 1/200 action figure. Articulation-wise, better than GFF or MSiA
- super HCM Pro : enlarged and more detailed version of HCM Pro
- MSiA : non-scale action figure, but approx 1/150. Less detailed among the 4, and made by softer PVC

Nah, I think at least Exia's MG was already in development, considering its popularity. It's just the development take long time too. The fastest record for a MS in a gundam series become MG is one year(after the series finish aired in Japan), which is MG Aile Strike (we talking about completely new MG here, not a recycled design).
Although Exia model kit now already have good articulations and details, it still cannot beat the articulations and details of recent MGs, Thus. I believe MG Exia will include same features as recent MGs such as:
- articulated fingers
- inner frame
- openable cockpit
- improved joints

And although this is a mere hope, Bandai should include LEDs in the chest area
