Personally, I think it's just stupid. The IS350 has already got more than enough ponies, why add more? It uses more fuel, and is maybe heavier. Japanese automakers should stick with I-4 and V6 engines, it's what they do best. The 5.0L engine is guaranteed to have some type of problem. Lexus should make an IS coupe, that would be a little bit more reasonable IMO. It's not that it's not cool, but I don't get why someone would get an IS500 when the IS350 is already so fun AND cheaper AND more fuel efficient.
