I think you missed my point. Tornado's letter specifically said the update kit applied to T-2000 with the stainless steel look - not to any other model year or style of table. They were very specific in their letter. Clearly, this was done by Tornado because they believed that this model table had certain changes which they believed should have been included or available to the consumer for that model and model year. Since the free update kit was only for a limited and recent model of table, why does June 1 make a difference?
By their actions, they have treated this like a vehicular recall/promotion for the current model year similar to where all purchasers of, say, a 2008 Ford Explorer will have their airbags replaced, free of charge, for whatever reason (defect, consumer complaint, change in federal safety standards, etc.). What if Ford announced that, even though all 2008 Ford Explorers were made in an identical manner, on the same assembly line, regardless of what month they were made, only those purchased after a certain date were eligible for the free replacement. It makes no sense from a customer relations standpoint.
Where it does make sense is, probably, from a financial standpoint from Tornado. I would be willing to bet that a very large percentage of the 2008 T-2000 Coin-Ops with the stainless steel look were purchased before June 1, 2008. Thus, Tornado is, in reality, giving out very few free "update kits" and is, in fact, charging everyone. If that is the case, that is fine. I just wish they would be honest about it.
