It looks legit as legit can be at this stage!, even has set numbers, promo kit and stuff.
Cheers. I was going to say it does seem pretty detailed and mostly acruate as far as we can tell. However, the code for the TIE Fighter is actually the code for the Sandcrawler, so its not entirely accurate.
If the UCS Helicarrier is confirmed it would make sense for it to be released around the same time as the Age of Ultron film, so I wouldn't be surprised to see that shift towards May rather than be as early as Feb.
