A big LEGO Batman set planned for 2014?

The clue comes to us from the list of competition rewards "The LEGO Batman 75th Anniversary Building Competition"currently organized on ReBrick at the end of which the big winner of this competition will receive a substantial prize detailed below:

Four LEGO Batman sets already on the market (76010, 76011, 76012 and 76013)
Three LEGO Batman posters (Probably the three visuals that I have already posted on the blog here et leaves)
A copy of the LEGO Batman 3: Beyond Gotham video game
An exclusive LEGO Batman comic
A upcoming LEGO Batman product in 2014 ("...An upcoming 2014 LEGO® Batman product... ").

Knowing that the four LEGO Batman sets already released are also offered to the semi-finalists of the competition and that the rest of the endowment is still anecdotal (video game, posters, etc ...), this LEGO Batman product to come in 2014 seems to be the "big" prize in history.

We can therefore venture to formulate some interesting hypotheses: Tumbler UCS? Vintage UCS Batmobile? Exclusive set out of nowhere focused on commemorating Batman's 75th birthday with Batcave filled with minifigs in costumes from all eras Batman went through? Box gathering different Batmobiles?

I'll let you think about it and make your predictions, we will undoubtedly be definitively fixed during the next San Diego Comic Con which will take place at the end of July. LEGO will undoubtedly not fail to take this opportunity to unveil a new major LEGO Batman box ...

Update : The reference 76023 UCS appears in the Brickset inventory in the Super Heroes DC Universe section ...
