There are two devs (plus myself) working on making a stable Windows build, can't tell eta but rest assured we are working hard on it.
It will be compatible with old wallets, unless there is reason not to.
Good to know pallas. Also when it's done and we have a flawless wallet and a block explorer, it would probably be a good idea to start promoting the coin through social networks like Twitter and Facebook. Having slack channel would be nice too. It would be a good way to get people's recognition and interest. Especially during this altcoin boom.
Also, being listed on a few more exchanges like Bittrex, Cryptopia or Yobit, or even try to get back to Poloniex would also be of benefit to this project.
The altcoin boom that is happening right now is just a great time for XCN to present itself
P.S. Devs, I assume this twitter account is not active any more:
https://twitter.com/CryptoniteCoinP.P.S. Any plans for the future development?
As soon as the wallet is ready, I'll do my best to first re-activate btc38, then get relisted on poloniex.
I personally don't like cryptopia because they do a lot of fake orders to boost volume, and who knows what else.
Besides, 3 exchanges would be enough, maybe bittrex would make sense though.
Maybe bitfreak knows about the twitter account.
I hope the community can help us with promotion :-)
About future development, I've got a list of basic improvements to implement (after the wallet is finally fixed and stable).
Furthermore, if you look thru the site and the wiki, there are some ideas for improvements by the original dev, that have not been implemented yet (for example trie pruning).
I suspect you @btcma is a Scam, troll 
or, maybe 
rubishh here on BTC.
