It's still a mystery as to why Bandai chose to re-release two kits in updated colors instead of making a brand new kit to market alongside the new Unicorn series. But hey, any release is fine in a line whose priority level seems to have been bumped down considerably.
Bandai seems to show us that they still have a few tricks up their sleeves when it comes to Gunpla. Sure, only one of the newly announced kits are actually new, but the "remastered" one and the "re-designed for a new scale" one are enough to merit serious consideration.
The new 1/100 scale Gundam model kits are on display in All Japan Model & Hobby Show 2015. We actually guessed these a few months back... hire us Bandai.
More Red Zeta images up and its sweet!
