I think you're misinformed. It will have the same "size" battery, as in the overall capacity. I don't believe anyone has said it's the exact same battery. So the battery alone, at the same capacity, could have better performance(there's more to a battery than just the capacity). Additionally, as was already mentioned, the newer processor is even more efficient. Other random components in the device are probably newer parts(even if they have the same numeric rating specs) and are also probably even more energy efficient. The screen is the same resolution, but not the same screen. So it's probably even more energy efficient.
All of that said, I would expect similar if not increased battery life, on a tablet that most would agree is fairly good on battery life already(it's not "great" by any means, very few tablets reach that level today, but it's good enough for most to last a week or so with moderate use).
I don't think I'd buy a regular Tablet Z right now with the Z2 Tablet coming out within the next month or two, unless it was under $350USD(assuming the new 16Gb wifi model will sell for $500USD as the previous one did....here in the states).
