Just got off the phone with a Lexus rep, and this is what he told me. The GS series will come out with the GS330, which will, of course, have more power, and have more sporty features such as weight reduction, more low end HP, and a better e-shift. The GS 4 series will have upgrades also in power, and will offer a AWD version. Thats power to ALL the wheels!!!! Just imagine that with a supercharger! They are also considering a LTuned GS500 series which would go against the BMW M5. This would be in limited production, and have a factory supercharger made by TRD. The IS300 will also get a boost in HP (IS330), and be offered in a AWD format. This is to go against the BMW 3 series, and the Audi S4 series. Lee
