I read (and I'm still reading) a thread about new XS++ on Se-Nse and they say that they are trying to make a stable version for Linux (some of them hate Windows :D, but I hope they'll make it for XP/Vista) which can flash like 3.1 version (, but it will have CID 53 support) and they said that XS++ which will support A2 platform will come out after 4.1 or even after that version.
4.1 makes happy only Linux owners because they couldn't use normal XS++, you just make big hype about it. ;)
