It's probably just a coincidence, but does anyone think it's somewhat suspicious that only shortly after Eberron has given us the shifters, people who are descended from lycanthropes, we now have a Forgotten Realms article which gives us a quasilycanthrope template? It's not the same, but still, it makes you wonder...
Right, not the same. Wonder about what exactly? Shifters is a neat race idea, anyone can port the race into whatever game they want, WotC included. Anyhow, it goes along with what has been produced core and FR-wise in covering the entire spectrum of +1 LA to higher LA's and the template-levels. Really, just an inevitable continuation of what has already been produced. In fact, Shifters or just Lycanthrope-touched just as there are Feytouched, Planetouched, etc. so Shifters themselves were quite inevitable and they appeared in Eberron because they hadn't been put into a setting just yet (WotC setting anyhow).
I've always viewed FR as the cutting edge and test-bed for new D&D mechanics, with some of the best game designers taking part (let's face it FR products produce quality stuff, so much so that we see some of the best imported into the core books with 3.5). Pushing the envelope and watching the synergy between new rules, feats, spells, what-have-you and the best bits, as I said brought into the core game. Not to mention the best setting book to have ever come out...still (I mean come on, the FR Setting Book came with a MAP for goodnes sakes! *gasp*)
If you love having options and greater complexity/sophistication in your D&D game FR is the way to go. If you like things simpler, less developed magically, and fewer rules to have to worry about then FR is not for you. Plain and simple, if I want to run a great cuthulu-ish D&D game I run Midnight or homebrew stuff, but for swashbuckling/high-adventure/high-magic/epic-style play I go FR. If I want Lord of the Rings I play a homebrew mix of Midnight and core rules.
