The Tungsten T5?

Ok, the cat is out of the bag about the new Treo Ace/Treo 650, but for their flagship PDA is palmOne planning on skipping over the Tungsten T4 and going straight to the Tungsten T5? We've already seen two competing sets of (probably fake) specs for the supposedly forthcoming Tungsten T4,
but according to some German Palm-related website we've never heard of before (you can probably tell we're just a little bit skeptical), palmOne is working on a Tungsten T5 which is supposed to have a 400MHz processor, 256MB of memory, Bluetooth (but possibly no built-in WiFi), and come out in October.
