Is anyone else getting the impression that the recent plethora of launches is being sped up as a result of Musk/Bezos competition?

SpaceX own launch rate is behind their own optimistic schedules, even accounting for the CRS7 failure. They are simply catching up to their own schedule, going as fast as they can. Long term? Maybe. But short and medium term term? Heck no. Blue Origin is far too secretive to have that kind of effect on anyone.

I defo. get the feeling there is some friendly billionaire competition going on here...!
Posted this in another thread about the recent Raptor contract but it really belongs here.Just looked at the SpaceNews article for the BO test flight yesterday and there is one tidbit of information and that is that the BE-4 prototype tests NLT EOY 2016. This is 1 year in advance of SpaceX so you are correct that SpaceX is likely to increase their spending to do their prototype test for Raptor NLT EOY 2017. Also this means that by 2019 there will be a possible 2 MethaLox 500Klbf class engines in production. Things are moving quickly and SpaceX needs to keep moving ahead rapidly or they may get left behind in the reusability race that has started.This also means that if ULA continues sufficient funding of Vulcan then they could fly the first MethaLox orbital 1st stage NLT EOY 2019. SpaceX would not be far behind with a 1st stage MethaLox vehicle NLT EOY 2021. Their development may see an acceleration.There is a competition starting but it is for a highly inexpensive reusable 1st stage and the competitors include SpaceX, BO, ULA and ESA. I am wondering if ULA may change its Vulcan design to allow for later propulsive land landing recovery, since Vulcan is still in design (paper) phase but with a BE-4 looking like existing with exact performance values and (form fit function) the design is likely to quickly transition to critical design and production. SpaceX's effort is a year behind and that will spur them to speed up.
I don't think so. Certainly there is a competition for visibility by putting out slick commercial videos of the achievements thus far. But many of these companies started out around the same time, in the early 00s coming right after the internet boom and the time it takes to develop technologies like this is hard to compress, even with a ton of money. So right about now, they're on the steep ascending part of the curve, when all that trial and error comes together.
For orbital launches the F9 can be considered as the first generation VTVL reusable first stage and the BE-4 and Raptor powered first stages to be the second generation VTVL reusable first stages. The difference being that the MethaLox vehicles are likely to have twice or more times the number of flight life than the F9. Plus the refurbishment costs may be lower for these vehicles as well such that on a comparison the per flight costs of these second generation 1st stages may represent a real reduction in costs of as much as $5M per flight. Making the cost of the 1st stage per flight as a percentage of the flight costs <10%. Now add a reusable US and the costs can drop another $10M per flight get the per flight prices below $20M. But it will not happen overnight. These second generation 1st stages will be showing up somewhere around 2020-2022 ULA's Vulcan notwithstanding which may fly as early as 2019. Unless ULA changes their minds about VTVL, Vulcan would be classed as a first generation reusable 1st stage even though it could have a large flight number for the engines the costs per flight will still be significant.
