I just played a bit of the arcade version last week during my overseas trip (@ Namco Wonderpark Plus in Causeway Bay, Hong Kong) and I can that this is no game to be underestimated with.
Also tried it in Macau with their super deluxe cabinets that took lots of the space (probably worth eight maximum tune 3 dx cabinets put side-by-side) and it is really sweet. If you haven't tried playing it, then I suggest that you do so ASAP (when possible)
