I'm interested in replacing my R50 before it gets too old
I want a large screen, high resolution, fast processor and good battery life.
However at this time, I don't see any models of the T520 that have a FHD (1920 x 1080) display, quad core processor, and the NVIDIA discrete Graphics Processor with Optimus technology to give me good performance when viewing training videos, and good battery life when using normal Offices software (including Lotus 123). The closest I can get is the T520 4239-26U, which should be excellent on battery life (FHD, Optimus, 128G SSD), but comes with the i7-2620M dual core processor, not the Quad Core I am interested in.
I can get my desired options now, but I have to go to a W520 Workstation Thinkpad.
Would be glad to hear from anyone regarding pros and cons of going to a W520, instead of waiting for the configuration I want in T520?
I am not a gamer, and do not do multimedia editing or preparation or run CAD. It appears that similarly configured models of the T520 versus W520 will have similar weight, battery life, cost and performance.

I agree with the above advice, but I'd still love it if anyone had information on availability as originally asked.
(I do CAD work, and definitely need better graphics ability. Games would be nice too, but not required.)
I'm running a T60p, and the CAD crashes regularly due to lack of RAM. I'm very much looking forward to upgrade but am not sure how long I can stand to wait.

I think that the 4242-48U and or 4239-26U will be the closest you will get and they have the dual core i7 chip. I believe those are a couple of combinations that (due to teh NVIDIO graphics) won't be able to be ordered until Mar 29.
I, too, want the I7 2720QM chip so likely will go with the W520 in a week or so when they are out.
The other want is the RapidDrive (addition of an 80GB SSD) option with the HDD. That is not yet available.

Thanks a lot for the viewpoints and advice.
Let me share some of my research, which appears to be contrary to what most would expect. It is based on http://www.lenovo.com/psref/pdf/psref395.pdf version 395 of the Personal System Reference.
T520 models with NVIDIA Optimus technology have the NVIDIA NVS 4200M with 1GB VRAM
W520 models with NVIDIA Optimus technology controlled discrete graphics cards have a choice of NVIDIA Quadro 1000M or 2000M with 2GB VRAM
Page 123 memory section points out that W520 dual-core models are limited to 2 DIMMs with 8GB total max, while quad-core models can go to 16GB max. using 4 DIMMs. The T520 datasheet indicates maximum memory with any processor, is 8GB using 2 DIMMs
The Optimus technology, assures me that I will not be using battery to support the extra GPU, unless the application mix can benefit from the GPU rendering.
ProVantage has many models of the W520 for sale now, some with Quad-core processing, and Optimus.
The T520 models with Quad-Core processors, have not yet gotten into the Reference book.
Both systems have a full and a half PCIe slot and their I/O features are similar, except the T520 has a 4 in 1 Card reader and an additional, the W520 has 2 USB ports that are USB version 3.0 (all T520 USB is 2.0). Options for HD, SSD, LAN, WLAN, WWAN,
T520 models with Optimus have 1 combination USB 2.0/eSATA port, all W520 models have this port (they all have Optimus)
I get a new P.C. on about a five to seven year cycle, and want to make sure I have enough horsepower and memory to handle future software and OS. When you spend time waiting for a machine to boot or come out of hibernation (many times a day for me!) a high speed CPU becomes important. I generate/regenerate 10 to 15 thousand record databases from my spreadsheet and it is taking up to five minutes to do that currently. I want it done fast. I plan to get a 27++ slice battery to complement a 55++ 9 cell main battery. With either a T520 or W520, this should give me 15 to 20 hours of usage on battery.
Also, It is my understanding that the Intel Turbo-Boost technology for the 2nd generation dual-core and up, will throttle clock speed up or down, depending on the workload, and that this will improve battery life. http://www.thinkingneverstops.com/thinksmart.php?C
If you configure a mid-level T520 or W520 the same options, you might be amazed at how close the bottom line price ends up, especially with FHD displays and Optimus technology graphics.

This modell just popped up in Germany:
Thinkpad T520 NW93UGE/42433UG
i7-2720QM (2.2GHz), 4GB, 500GB 7200, 15,6" FHD 1920x1080 LED, 1024MB nVidia NVS 4200M Optimus, DVDRW, HD-Cam, Intel a/g/n WLAN, BT, UltraNav, UMTS, FP, Sec. Chip, 9-Zelle, Win7 Prof. 64, 3J. Garantie (VOS)
Looks like pretty much what you are looking for.
