Yup. If Walmart has it, it'll likely be back in the electronics section somewhere. They also usually carry the extra stand that'll bump the mini cab up closer to full height. I haven't seen any of the ones in the upper picture in the stores yet, but it may just be a matter of time.
The MK cab isn't even on the Wal Mart website though. Nor Best Buy, Target, GameStop, or P.C. Richard and Son (those are all the stores from the Acarde1UP website that are local to me). Is it some kind of secret stock item?
Also I checked local Wal-Mart inventory with Brickseek and I'm not seeing any of the new cabs yet. EDIT: followed my own advice and found it on Brickseek via Google. https://brickseek.com/walmart-inventory ... =562017574
Yeah, I wouldn't pay $300 for one either, but for $200 I'd definitely consider it. I think Walmart was selling them for about $250 around Christmas time, but even that's a bit too much for me.
I don't think $300 is that bad, all things considered. If you wanted to make a Mortal Kombat II cabinet, you can get reproduction side art, CPO, and marquee. But the cost of the repro art plus the lumber, hardware, joystick and triggers, et cetera, and a Raspberry Pi or a PC and a monitor... $300 isn't too bad.
Somebody just posted four of the 2018 cabs for $600 on my local Facebook yardsale group. That is pretty tempting. Pretty sure the wife would veto it though.
