I been in on TH and now have Full Throttle on order. I find the concept of Heighway much more appealing than that of JJP.
Do not get me wrong, the LCD of JJP is just stunning but I think in the long run the functionality of the Heighway LCD will win over the 'movie' LCD of JJP.
It is about pinall, not about watching a movie.
And indeed Heighway will also evolve when it concerns the use of their LCD. Many options have already been spoken of for implementing in Alien.
