Although Ganz has never come out and said it and probably never will, the younger Webkinz customers and collectors probably have a harder time coping with it, but the Lil' Kinz line has effectively been discontinued (or put on hiatus is a better phrase for it.) Not releasing a Lil' Kinz Webkinz since last July is very indicative of this, plus the introduction of the Zumbuddy Webkinz line and two new Signature Webkinz offshoot lines is more than enough proof that Ganz's interests are elsewhere in other product lines. The Signature Webkinz in particular has skyrocketed in popularity due to their larger size and softer nature. Other indicative proof would be that as of late, bird and fish styles have been introduced as normal Webkinz as opposed to Lil' Kinz. If the line was going to continue, would have thought the Lionfish, Caterpillar, Pink Cockatoo, to name a few, would have been Lil' Kinz instead, as they're typically smaller animals in nature.
However, here is the list and product codes from an old Ganz document of Lil' Kinz styles that were going to be released... but were scrapped when Ganz decided not to make the new lil Kinz. Will some of these styles be reconsidered and introduced as full sized Webkinz or small Signature Webkinz? Only time will tell. This list is 100% valid as it was sent prior to the announcement of Polka Back Fish, Budgie, Oriole, and Tomato Clown Fish, and then one by one they were announced.
Here's the list of those who didn't make the cut, but may make a reappearance in the future in some form or another -
HS508 - Hamster
HS509 - Warbler
HS514 - Parrotlet
HS517 - Grey Mouse
HS518 - Butterfly Fish
HS519 - Pink Scalefin
HS520 - Blue Parakeet
Obviously not every variation will make the cut as there are typically about 4-6 new Webkinz issued each month. Some are the new signature series to compliment the regular full size Webkinz version. But it looks like the Lil Kinz seems to have taken a back seat to all other Webkinz at least for the time being, if not forever. A cheaper alternative and a joy to many that considered them the babies to their mommies and daddies.

So if you are wanting these Lil Kinz Webkinz as upcoming presents, you may want to start stocking up on them before they are all gone. Especially since the newly released Webkinz and the Signature Webkinz series don't seem to be slowing down any for the past several months. Don't necessarily count on the prices to go down for a long time on the rest of the Webkinz collection. The Signature Webkinz in particular are usually doubling in price at least. It may be years before that happens or might be the Webkinz variations that you don't like. Now that you have the information, it is up to you.
