I'm excited about it. I played this game for years and nothing else is like it. Don't think anyone is surprised they're not patching anymore but the private server thing is great news. Hopefully someone knowledgeable in both their software and the old school AC pvp game puts something together.
I tried going back to the game a year ago but it's just not the same. Years of shitty patches have ruined the pvp experience and the remaining playerbase is unique to say the least. The grind is also pretty silly to get back into it, you're looking at 1-2 months of 24/7 grinding (everybody bots) to max out a character. Everybody just buys accounts and currency now.
I'm sure bots/scripts will always be part of AC (not a bad thing imo) but if someone can rewind the game back to 2002 (with a few balance changes) and get some trustworthy people running it I wouldn't be surprised to see a few thousand people in 1 server again. There's going to be a huge skill gap though, the animation breaks people can do on a mage in the game now are pretty crazy
