这个问题有些不太好翻译，因为"同系列新品"的英文说法是根据上下文而定的。
如果指的是同一系列的新产品，可以用"new additions to the series"或"new products in the series"来表示。例如：
The company has released several new additions to the series, including a new phone and a new laptop.
We're excited to announce the latest new products in the series: a smartwatch and a pair of wireless earbuds.
如果指的是某一系列的全部新产品，可以用"new pne of products"来表示。例如：
The company has unveiled a new pne of products, including a range of home apppances and smart home devices.
We're proud to introduce our latest pne of products, featuring innovative designs and cutting-edge technology.
希望这些例句能帮到你！
