DJ,
I myself do not have the 'desire' to have a full harddisk-recorder implemented in an arranger keyboard. For recording dedicated HDD recorders are available.... they are affordable, compact and "fit for purpose".

An example :
Would you think the same, when your TV set comes with an integrated Telephone, FAX, calculator and built-in microwave ??

In my view an arranger's most important function is .... arrange the music you play.

What I heard :
T2 porbably has a built-in 4 track HDD-recorder. On the prototype-picture there is no XLR-input at the back of T2.
