http://www.freescale.com/files/training/doc/dwf/DWF13_APF_NET_T0795.pdf is a nice presentation from April 2013 I just stumbled upon now. Interesting things in it (among others):
Page 8:
"We absolutely stay committed to our Power Architecture and our new e6500 core delivers an unmatched performance/power ratio for the years to come. We continue to invest in this area. [...] We will pick the right core for the right segment/application in alignment with our customers and networking expertise. [...] ARM high end cores have been part of FSL portfolio for years and require minimal incremental investment to leverage for Networking Freescale will use standard ARM offering where possible Freescale has a fully negotiated architectural license ready to exercise if need"
Page 10:
Core roadmap until 2015 shows Cortex-A53 ("Apollo") and Cortex-A57 ("Atlas") as well as the e6501 core (adding virtualization interrupts) for 2013/2014, all in the current 28nm process. For 2015, two new cores in 20nm process are shown. I believe that at least the higher performance one ("NGC" with multithreading, higher single-thread performance, directory snoop filters, low-latency clustered accelerators) is supposed to be a new Power Architecture core succeeding the e6500/e6501 core. The lower performance one ("Helios") may be ARM (which would mean a not yet announced core by ARM Ltd.) or Power Architecture.

QorIQ LS2045P: - 4 x e5500 at 1.5 GHz - 2 x DDR4 - 6 x PCIe 3.0 - 2 x SATA3 - 2 x USB 3.0 - 8 x 10GbE - 16 SerDes lanes (8 for networking, 8 for PCIe) - LCD controller (DIU)
Page 24:
QorIQ LS3400P: - 20 x e6500 at 1.5 GHz - 4 x DDR3 - 6 x PCIe 3.0 - 2 x SATA3 - 2 x USB 3.0 - 2 x 100/40GbE - 24 SerDes lanes (12 for networking, 12 for PCIe)
Page 26:
Mention of T3-Series.
Page 33:
Mention of QorIQ T4400, which should have 20 e6500 cores.
Edit: http://2014ftf.ccidnet.com/pdf/0016.pdf (page 14/15) from May 2014 has the information that QorIQ LS3 series will have "ARM and Power Architecture cores".
