According to the admins on the formuler message board, the Z7+ will not be getting the MTVOL-2 major software upgrade and new hardware must be purchased if you want the new software. They claim there will continue to be updates to the Z7+, but the new overhauled software will NOT included.
Can't see spending the money personally. Only to likely be told to pony up again on the next major software revision? No thanks.
Don't worry, soon Formuler will be totally banned from sales, unless they licence Stalker from MAG, they got banned selling in Germany 2 days ago, expect it to be Europe wide soon and across the Atlantic too.
