The KIDDY GiRL-AND official site database has (finally) been updated with information on some of the new characters
Di-air - 7-year-old companion of Ascoeur and Q-feuille and ES-member apprentice apprentice. Her special ability is called "A-quare" (エイ・キュア ei kyua)
T.A.M.A - stands for "Trial-type of Assemble-system & Multipurpose Automata", a Gene-tec beast that can transform into anything. A mascot character usually disguised as Di-air's pochette until transformed by her kiss.
Trixie - Ascoeur's sempai and one of the strongest ES-members, a cheerful older sister-type adored by everyone. Her ability "Power-S" (パワーズ Pawaazu) allows her to manipulate space.
Troisienne - Trixie's partner and one of the strongest ES-members. Mature and gentle but with an unexpected childish side, her ability "Particle-T" (パーティクレットpaatikuretto) allows her to manipulate time.
Why are Trixie and Troisienne's abilities named "Power - [letter]" and "Particle - [Letter]"? That's just suspicious as all hell. I'm really getting more and more into the show though and am happy to see it finally moving forward. Though now I'm with you and wondering what they did with the actual opening animation. Maybe they only wanted to make one and it was just too spoilerific to put in just yet? ie. we won't see it until Eclair and Lumiere come back?
Speculation...
It isn't uncommon for series to have two OP sequences to reflect plot developments - Kiddy Grade itself had two (and a third on the DVDs). Digimon used to have shadowed figures that would be revealed around the halfway point.
The Stellvia OP was footage from the first episode all the way through, Trinity Blood used footage from the first few episodes (I can't remember if they did a proper OP later though). Kiddy GiRL-and's is less lazy in that it does at least change each episode - somewhat akin to the Vandread Second Stage OP, which recycled scenes from the First Stage OP and inserted a few scenes from the upcoming episodes, or the ED for Gatekeepers (or was it GK21? Maybe both) which reviewed key scenes from the episode itself.
Saphir and Rubis are now up also:

Names are now confirmed, not that I never had any doubt about these two anyway. Their powers are called "Frigidity" and "Zoanthrope" respectively.
