I loved TextMate.

But I think the facts speak for themselves now...

- their site is now little more than a vanilla bootstrap theme

- their News section hasn't been updated since 2014

- the blog appears to be miscellaneous developer notes that may or may not even be related to TextMate

...I'd agree with the sentiment that development appears to be dead.

That said, I think Sublime is as worthy a spiritual successor as any. (It also may be the biggest reason for TextMate's demise.)
