Someone just mailed me a link to this with a question about it so here goes:
Sorry to disillusion you but the only Technics features you will find in the Pa1 or G70 will be there by the sincerest form of flattery - copying. The development time lags are such that any Technics employees will not have had any input and anyway do not own any software rights which remain within the company. The only person with the knowledge to be in any position to do so does not work for Korg.
Also the only ex-employees of any significance to move to Roland is Chris Halon, hardly a lot, but you would have to go back quite a few years now to count Dennis Houlihan who left Panasonic to become president of Roland(US).
