There are still fans of Super Mario bros Z (or SMBZ for short) who want more episodes to be released even after Alvin Earthworm cancelled the series. They're multiplying OMG! In case you fans didn't notice, he closed his deviantArt account after leaving it inactive for so long. He likes to do his furry art more than sprite animating because the latter as we know it is very tedious work. I'm not quite a fan of furry art, but it's what he started over ten years before starting SMBZ and it's like his signature hobby. Scratch that, it is.
The constant demand mentioned in his rather tragic announcement referred to one of the factors that contribute to his stress in life, along with his kitchen porter job. Sure, it sucks that the series can't be concluded properly and I strongly agree with that. But as far as I'm concerned, Super Mario Bros Z is cancelled PERMANENTLY!!! Because like I said, he closed his old account on dA and sprite animation may be a thing of the past altogether.
Now all we can hope for is that Nintendo and Sega work together to make an epic Mario & Sonic RPG. As Alvin's biggest fan, I ask you all to get over it and find better things to enjoy. Have a nice day.
