Agreed. Lexus has struggled to keep the showroom fresh and brand interest high when they launch so many products in a short timeframe, and then have nothing new for years afterwards. Think 2006 - 2008 when we had all-new IS, ES, GS, LS, and LX over just a few months, then only had RX and GX over the years that followed. Then we entered into 2012-2014 with new IS, ES, GS, RC, NX and refreshed LS over ~2 years, and they are just now emerging from that slow period.
If Lexus is launching all-new NX, RX, TX, GX, LX and RZ over ~24 months, I hope they have some other tricks up their sleeve around 2025-2028 or we will be right back here talking about how the brand is stale and doesn't have any new product. Keep in mind UX, LS and ES should also be redesigned over this time period as well - maybe IS too. Right now it feels exciting with so much new product ahead of us but I have been around long enough to look at the ~4-5 years after this next 2 year blitz and be a little worried about the bust after this "boom."
It's cyclical where product becomes so stale that Lexus has to redesign everything in a very short amount of time to try to keep up. One new CUV/SUV and sedan/coupe per year would help keep showroom traffic steady and maintain momentum for the brand, but I know sometimes it is easier to retool and accommodate for multiple models in a short amount of time, especially with TNGA. Still... the product cadence seems like feast or famine, and could definitely be smoothed out a bit.
