Anyone who might now is likely under NDA and thus cannot tell, and everyone else is on the same page as you are :-) Just with computers there's never the right time to buy stuff. But with a good deal I wouldn't see a reason why not to get it. (After all there's not much choice in this type of Amplifiers, you basically have the Line6 Amplifi and maybe Spider, the Yahama THR10 (cannot compete with 150W, limited effects), the Boss Katana (much more expensive) and the Blackstar (more expensive and limited effects) – so Amplifi gets you most bang for your buck I'd say. But of course depends on what style of music you play and whether you already have your favorite pedals/effects unit).   But let's assume that Line6 will release a new model: If it would have the HD effects then, it would be prices more like the Firehawk, so a lot more expensive (and then I'd not consider it as a update of Amplifi line, but new release of Firehaw). If it is just a refresh with minor updates (like e.g. usb charging port or additional i/o FX-loop or maybe a way to switch banks on the unit itself or integrated wireless like the Spider): would you be happy to pay the MSRP of the Amplifi for that, or would you rather save the money with the clearance deal? I don't think Line6 will lower the price in a hypothetical refresh, as Line6 already is at the lower end compared to similar products. And Powercab alone costs twice as much...
