Yes, thanks for the hint, MKNews said that MK "has begun" to record songs for a possible future release.
However, last November, when that Gibson Guitar video came up, Mark mentioned that the new guitar was immediately used for recording.
Plus in the Tracker video he said, "I come here (BG) to record, not to write". So he works already longer on recording new material I guess.
Or maybe that Gibson recording was for that Playtime Deluxe one shot. The video ad recording might have taken place some time before.
