I remarked that these sets include many spare figures (the stormtrooper in the Tie Defender set, the Talz and the battle droids). Anyway, let's comment!
The freeco bike is well designed and seems to include a Talz warrior minifigure. This is particular because it seems to be a unique and exclusive minifig, which are, usually, included in the bigger sets. A few of these sets would be good to recreate the battle of Orto Plutonia. The other minifigure is unclear. It could be Obi-Wan, Anakin Skywalker or a Pantoran soldier, a minifig of a few interest. I think the vehicle will include stickers for the front details and republic insigna on the back. I hope the cockpit is airtight. Not easy to do at this scale, but still possible.
Finally, by judging the piece count, its price will probably be set between 15-20$. This is relatively expensive and, at this price, it will be hard to buy many and recreate the battle. And, although the set may be good, the idea is not. The only use I see for this set is the battle of the Clone Wars episode "Trespass". You cannot really use it for ground scenarios that are not taking place on a snow world. For this reason, its use is very limited.
I'm glad that Lego is finally releasing a remake of the droid tri-fighter, that we have seen for the last time in 2005. However, judging by the picture, it seems oversized. The minifigures (rocket punky battle droids ) will only contribute to increase the price. The fighter seems to include two flick-fire missiles and the front cannons look interesting. I wonder if the main bubble includes another of these buzz droids. I think I can foresee one but I prefer to wait for clearer pictures. Like for the freeco bike, it will be hard to acquire a fleet of these, as the price will probably be set between 25$ and 35$. It doesn't look very exciting but is a good addition to a CIS army and unlike the freeco bike, this set can be used for many stories, scenarios and battles.
The Tie Defender set is a real beauty of design I see that Lego has finally buried his blue and black design for Ties and is turning to more realistics gray and black. The fighter looks great with its three "V" style wings. This set is from the Expanded Universe and a welcomed addition to any OT fan collection. It has many different uses and is another piece in the Ties family.
The minifigures themselves don't look very exciting. The stormtrooper is a common figure but one more is always pleasant to have. The Tie pilot itself is also a common figure but this one looks different. Maybe it is because the bad quality of the image doesn't show all of the details. I do not think this is a new helmet because there are no variants of space Tie Pilots. I am looking forward to this.
I am satisfacted to finally have the confirmation that there will be a rebel battle pack next year and that I will not be forced to buy zillions of Echo base sets just for the new rebel troopers The vehicle is similar to the 2008 scout speeder but share come characteristics with the Pirate tank : the turret. I also hope that there is enough space on the front of it to put another soldier in. It looks like the set will include two long rifles and one short rifle. But, as a battle pack never comes without four individual weapons, it will probably include another short rifle. The pilot is a particular addition because it is the first set to include one that is not a starship. This will help to diversify my rebel army As for the piece count, it is an error. Imagine if it was not! I sense that this set will become a must-have to elaborate Hoth dioramas and scenarios. Nice job, TLC
Finally, the snowtrooper battle pack. This is the only set to include a good number of snowtrooper at a cheap price. This is also the first white version of the new speederbike. Even if we all own zillions of them, this colour has an appeal to me. But I think the best element of the set is the AT-AT pilot. Yay! This minifigure is usually included in expensive and 100$+ AT-ATs. This time, everyone will be able to get his hand on one of these minifigs The other minifigure is unclear. It may be a snowtrooper, an imperial officer or a AT-ST pilot. The station has a firing mechanism for flick-fire missiles and a red light on the right. It is not great, but it includes a white plate, always appreciated. However, I do not like the Clone Wars packaging for this set and the rebel one as they are not from this time of the SW saga. It remains a great battle pack that will come in handy for the collectors and army builders
