I have some software that is not yet compatible with 10.9, and I'm worried about general stability of 10.9 since its still relatively new (might consider it around 10.9.3 if the software catches up)-- are the new (late 2013) laptops compatible with 10.8? Tried some searches but couldn't find the answer.
Got a tip for us?

Have you tried it? how do you know it doesnt work? Will it just not let you install? or will it not even boot a disk image with 10.8?
Pretty sure it won't let you install. You might be able to run it as a virtual machine.
Apple has never allowed downgrades on new machines. There is NOTHING wrong with Mavericks. I have it on all my Macs and it runs great!
As others have said it won't work because Apple did not create the drivers. Also, Mavericks is fine, I downloaded it the first day it was available and it has worked flawlessly since then.
What app isn't compatible with 10.9? There are very few apps that are compatible with 10.8 that aren't with 10.9
Well this is typical of new devices running the latest OS. It's designed to run Mavericks at a minimum.
I understand that's often the case, have you tried it or seen personally that it will not install/run?
Have you used it with all the specific applications that that OP uses and tested all the features in them that he uses?
No?
Oh okay then I didn't think so.
Its not that apple keys OSX to work on certain models, its that 10.8 does not have the device drivers needed for the new chipsets.
Apple used to key the install discs for each model, so you could not install OSX from your iMac onto a MBP but that's a different issue. Apple does not need to deal with that since they went with the electronic distribution.
The bottom line, is the legacy OS does not have the proper drivers to run the new MBPs
I have a external hard drive I boot from to do disk repairs and what not running 10.8 and it won't boot on my new rMBP. Also, any computer upgraded to 10.9 will not longer boot 10.8, even on my 2009 MacBook and 2009 MacMini. Your new rMBP can't run 10.8. Besides, there is nothing wrong with 10.9 that would keep you from upgrading until 10.9.3, which probably won't even be released until around May-WWDC of next year.
Thank you. Too bad though, now I have to decide whether to get an older model or wait...
Thats pretty messed up about locking out old OS's, but no great surprise I guess given how they handle iOS.
This is not true. I had a 2009 MBP that I had updated to 10.9. Sold it and re-installed the original OS install disk, which was 10.6 I believe. It did not fight about it at all.
Mac OS is software only, no firmware. So you can always downgrade to the OS that originally came with the computer with no issues.
Yeah I use 10.9 for everything, except if I want to play mine craft I boot into 10.8 on the same hard drive since mavericks has some problem with some part. So you can definitely still use older versions.
That's weird. When I try and boot 10.8 it shows a crossed out circle. I went and dug up my original restore disks and they booted no problem. So don't really know what this is about.
try reinstalling ML on that partition without touching anything else, don't format it. backup if you can.
