Respectfully, I disagree. The "ancient" design scopes are still in production purely due to popular customer demand. The DPO/MSO2000 series introduced several years ago was intended to replace them, but customers demanded both. The new TBS2000 series introduced last year includes 20M of memory standard, 9" display, etc. On other fronts - there is the new scalable scope platform that features analog bandwidths from 23GHz to 70GHz (200GS/s). In the last year or two there have been introductions of several new USB-driven Realtime Spectrum Analyzers with price/performance that is unmatched, while the realtime performance of the midrange RTSAs has been upgraded to >3M spectrums/sec. On the high end of things, a new ultra-wideband realtime spectrum analyzer as introduced 6 months ago that features up to 800MHz realtime BW. More recently, this year there is a new 8-channel, 16-bit, 5-10GS/s Arbitrary Waveform Generator and a new low cost Vector Network Analyzer. So, I respectfully disagree that there hasn't been anything new or innovative in the last decade.
All the gear you've mentioned is high end or very high end stuff and here I agree Tek still has good things to offer. Also, Tek was and still is good with making excellent probes.
I guess most people here consider <= 1GHz scopes (I'd call this mid-range) and low cost (~100 MHz) ones. In the former Keysight became popular (2k/3k/4k series), in the latter manufacturers like Rigol or Siglent took the market (and Keysight is trying with the new dsox1k series).
I feel that Tek somehow moved away from these markets, offering either old designs or things that are too expensive, focusing on the ultra professional gear instead.
Nothing wrong with such approach, but it is worth to note that the competition is going the other way - R&S, previously also only ultra professional gear maker, acquiring Hameg and releasing RTB series, Keysight introducing DSOX1000 series, LeCroy's affair with Siglent to fill the low cost market segment etc.
I'm quite curious about the new scope, maybe there are some cool innovations there - the specs are intriguing. But again, this is I guess slightly above mid-range segment so outside the pricing range of 99% of people here.
