Quoted from ecurtz:I believe he's referring to the LCD panels, which certainly didn't look like a standard aspect ratio to me.
Right, the current panels in TBL are 21:9 aspect ratio, which is ultrawide LCD. If I recall one of the guys said they were going for a less wide aspect (probably 16:9) and that's why we saw vertical bars on the old prototypes at expo with the updated gamecode. I really like the ultrawide screens and they are more expensive, so it will be interesting what they end up with in the production games.
