I was having the same dilemma and just bought a new Dialed In LE. Why? Here's my reasons and this is after playing about 5 games on a POTC prototype.

1. Dialed In is out now and the latest games come with all hardware tweaks. Early POTC will likely need minor hardware items tweaked or see small hardware changes with later production runs. For $9k+ I don't want to deal with hardware tweaks.

2. Dialed In is the smoothest and highest flow game I've ever played with unique shots.

3. More toys. Yup, I'll take the Quantum Theater, Drones, 5 magnets, Station 3 ball lock, QUED guy, trap door, and Quantum mechanic lady over the toys in POTC.

4. I prefer the ruleset on Dialed In over the rules of POTC. The rules in POTC are deep but I find all of the chapter modes and multiballs to feel very similar due to a lack of licnesed music, and licensed film actor audio / video. The modes in Dialed In all feel unique and each contain custom assets unique to that mode.

5. I prefer the Dialed In theme. No way?! How?! The theme of Dialed In is perfect in my opinion as it's perfectly integrated throughout the game. Since the theme is unlicensed no sacrifices had to be made due to a lack of certain assets. POTC has the POTC license but only in terms of images of the actors and Gibbs custom callouts, which are amazing, but I really want to hear Jack, Davy Jones, etc.

I may still get a POTC down the road but it won't be until a later production run and after seeing how the code is completed.
