I'll certainly take a look at the new 10 Commandments, but the current disc is pretty cool and I may well stick with that.
I think WB are doing a great job with their catalog stuff. Not animation for examples, but Wizard Of Oz's 3-disc and the recent Ben-Hur are fantastic, and even smaller titles like Narrow Margin and Point Blank are getting retored prints and commentaries. And then of course there is Kong!
For the amount they churn out, WB is my favorite catalog provider and has been for a while. Every title is carefully selected, you always get trailers and presented in the correct ratio, and extras if they're available (the Tarzan sets and Marx Bros collection for instance) and they often go out and create new material.
The Golden Looney Tune sets I think are terrific as well, and I was surprised to see the recent "Movie Collection" of The Bugs Bubby/Road Runner Movie and 1001 Rabbit Tales looking and sounding great in that two-pack.
Can't knock 'em in my book - every WB release I've picked up has been put together well and with exceptional presentations of the movies (after all, the very reason we buy these things)!
I agree about live-action though - my collection is roughly half and half made up of 1990 BC (Before Computers) and 1990 AD (After Digital), which is my cut off point in how I store things (leaving me enough room to add more to each "side").
I actually have a list of old features that I want to either see or add to my collection and I strike them off as and when they are released or pop up on TV to catch. I went through the IMBD and made up a year by year account of the titles I'm interested in, which is a pretty good way to kind of ascertain the amount of stuff one might end up with.
There are still loads of classic boxes out there I want (Thin Man, Astaire/Rogers, Val Lewton, Lugosi, etc) and tons of animation discs (the Image Entertainment ones are always great but slightly overpriced with no discount deals on them, so I often wait and then lose out. I only recently picked up Snafu from eBay, and am on the search for Uncensored Bosko 2 if anyone is feeling generous!)

Anyway, back to topic, and Paramount have really started to treat their stuff properly. The War Of The Worlds s was fantastic (great sound and pic), though one can't but help wonder if it is of course to make a last rush for standard DVD before they go Hi-Def.
Personally, I don't think HD is going to take off with the mass market at all. There is too much content flooding the market right now and so many collectors that it is essentially going to end up the LD of DVD collectors. I don't know if I'll early adopt, but I will go HD eventually, but certainly my black and white films will be the last to get upgraded if any.
