I was there a couple of weeks ago, and all the machines are his own made in Japan( I think that's what they said)so to do silver strikes which IGT own's the trade name on they would have to change the look's, and shape of so as not to infringe on the trade name of IGT. So maybe a differant shape, and color(silver covered all in gold might)could be used, but only he knows. Also his machines were in some of the other casino's like the Imperial Palace, Westward Ho,and Ventian if I remeber right.
