Max in the November meetup said that there will not be a SDK, instead, they will release some features over time. For example, Lisky. The February meetup probably is just re-branding, new logo, new website, and announcing / releasing LiskCore, introducing their new and bigger team, talking about what the science team is going to tackle and solve, introducing dynamic fees structure. All of those are exciting. But if you are waiting for the SDK, yo will be disappointed.
Yeah I recall him saying that in the video interview he did last year. However more recently on reddit he stated that when Lisk Core comes out, it will require everything to be updated. Everything needs to move together. So Lisky, Lisk JS, Lisk Nano etc... will all have to be updated at the same time to be compatible.
I think best case scenario - everything is done, tested, documented and ready to be used and presented Feb 20th. If this happens price will rocket.
Realistically this is what I expect.... Lisk Core 1.0 will not be officially released yet, but it will be "done" enough for Lisk team to demo at conference. They will claim there is just some final testing/tweaking and documentation left before making it official. Price should still rise.
