The first significant announcement to emerge from the German toy fair concerns Technic. Here's a Google translation:

New at LEGO Technic: CONTROL +

With LEGO Technic CONTROL +, consisting of new electronic components and associated free app, children and adults experience an even more authentic gaming experience. CONTROL + enables touchscreen control to provide realistic control and, for example, programming of simultaneous movements of the models. In addition, the app gives vehicle data of the model again.

LEGO Technic CONTROL + can be tested for the first time from 1 August 2019 with the replica of the Liebherr R 9800, one of the largest excavators in the world.

The LEGO Technic model consists of more than 4,000 parts, seven motors and two Smart Hubs and can execute several movements at the same time.

"LEGO Technic CONTROL + gives us the opportunity to create even more versatile LEGO Technic gaming experiences around the physical model. We are delighted to have Liebherr as a partner in one of the first LEGO Technic sets to incorporate this novelty, "said Niels Henrik Horsted, LEGO Technic Marketing Director.

The cooperation is also ideal for Liebherr: "The fact that the LEGO Group is offering our Liebherr R 9800 as a construction kit confirms our motto 'technology that inspires' on a small scale. The detail and functionality that the model shows are fantastic. We are confident that we will not only be able to inspire LEGO fans but also many fans from our industry, "says Gregory Schuh, Marketing Manager for Liebherr Mining Hydraulic Excavators.

Update: Andres has posted an image at Zusammengebaut and the price is said to be 449€ which will probably equate to £450 and $500.
