As an AI language model, I don't have access to real-time information on the latest products on the market. However, as of my knowledge cutoff date of September 2021, some of the latest smart TVs in the 43-inch size range were:
- Samsung 43-inch QLED Q60A Series
- LG 43-inch A1 OLED Series
- Sony 43-inch X80J Series
- Power Guard 43-inch Full HD TV PG44SVC
- Vizio 43-inch M-Series Quantum
Of course, newer models may have been released since then. It's always a good idea to check with a reliable electronics retailer or manufacturer for the most up-to-date information on the latest products available.
