To sum up.

The upcoming new TOTL Ketron arranger (probably retailing at 4÷5 k€) is basically the old well known midi arranger + some not well specified audio loops capabilities built-in.

The midi part has roughly the same specification of a PSR 1500 of 2004, or, speaking of current day arrangers, a Yamaha SX 600 (~750€).

The audio part consists of a few loops (how many not specified) that can only play at a fixed tempo and that are provided only for a few simple chords (not specified). It is safe to assume that chord inversions are NOT played by audio loops, as well as many common chords found in most printed scores (such as augmented, diminished, M7, 6, and all their combinations). Of course the instrument is fixed, as well as the effect(s) applied (backed in during the recording).
If you play a chord not available in audio probably the arranger will substitute it with a midi pattern, that will be (totally/noticeably) different from the audio loop (groove, instrument, effect), probably leading to a poor/unacceptable result.
For those willing to hire a band, a recording studio, a composer, and have plenty of time to spare, there is the possibility to develop their own audio styles (Ketron did not bother to make).

This is how I understood the whole new product being launched.
For me the audio part is totally useless, and considering the remaining midi part (as well as the much greater availability of midi styles), probably a humble SX 600 (same firmware as Genos) is much more bang for the buck! YMMV.

And by the way, an SX 600 can also be greatly improved by pairing it with our software arranger (free demo available) .....
