Yes, I believe there is a difference. The difference is in the part left out, the timing of death and indirectly, what is meant by death.
The NLT and the NIV make death something that can happen at some indefinite time in the future. The change was made to try to allow a semi-literal interpretation of the verses without the issue of GOD lying. The idea stems from the concept that death first entered the history after the apple is eaten and/or, death was meant spiritually as opposed to literally.
