Truth be known, there are things for which I find my old POD 2 more adequate than the POD HD. I'd be curious to test an XT

I have a POD X3, it was having a problem so I bought a POD HD.  I hated it, my X3 "Tones" wouldn't work on the HD and the HD effects were not as good as the ones in a POD XT and X3.  It also changed my tone slightly (lost a small amount of body).  I send the HD back and bought a almost new X3 off of e-bay. 
 
I use the POD with my pedal steel guitar and do not use any distortion type effects - mainly delay and reverb.  If I were using distortion the slight tone change would not be noticeable or an issue.
 
I have the POD Farm 2 and frequently use it with Sonar.

I had a similar experience when I went from an X3 to an HD500. It took me a while to figure out that the gain structure on the HD series is completely out to lunch. Every amp and every effect added cranked the gain higher and higher. I had to carefully create my own patches, and match gain levels at every stage. About 3 months into using the HD I finally got it all dialed in... The last time I pulled out my X3 it sounds like it has blankets over it. The amps (especially the clean amps) are so much nicer in the HD series... IMO of course.
 
What I miss more than anything is the 4 band parametric.

...  I have the HD500 so I'm still waiting for the new FW

I'm also on the HD500, but I won't be holding my breath for any firmware updates. Unless you have read otherwise... I'm sure this is going to be an HD500X update only.

... I've heard the Pete Anderson is great - AFAIK it is a modified Blackface amp of some kind.

Many, many years ago Line 6 modeled Pete's Blackface Deluxe for "his use only". It's a Blackface Deluxe with a more robust Power Transformer and Output Transformer... it's also setup to run on 6L6 tubes rather than 6V6's. I guess that kind of makes it a Super Reverb in a 1x12" deluxe cabinet.

Yes, it is coming. The Pro X and 500x got the FW last week, and the 500/desktop will get it this week or next week

I got the update for my HD500 last night. 
The new FW gave an option for a "global EQ", which I don't need since I only use mine in my home studio. 
 
The second part, the good one: 
It opened for the new expansion packs (like I don't have enough to spend all my money on ) and I got to install these (I've already bought them 2 weeks ago)
 
To sum up: my hands are tired from playing. New amps and Sonar Platinum in one week. 
The JazzChorus was just what I wanted :)

I kind of assumed that there would be an update for HD300 & 400 but now I'm not so sure... :/

I see the FW update is already available for the HD500. I thought for sure they would over look the older models... That's great news.
