Yes. Nintendo's output so far on switch in 2018 is a testament to why they need a budget handheld device. Their game releases has been laughable in 2018. I am a huge Nintendo fan and I purchased 1 first party switch game in 2018 (LOL, I don't even think that ever happened even for wiiU) and it's Mario tennis which is a third tier franchise (LOL again). They're trying to camouflage their poor output of games with a bunch of full-priced ports which is inexcusable and are essentially punishing people who supported them through and through in the wiiU days.
So why does all of this matters? Because a budget handheld would allow them to release games on a more frequent basis due to the need for smaller teams and cheaper budgets. This would allow Nintendo fans like myself to not have to wait 4-6months (or more, we haven't had a AAA Nintendo release since October 2017 which is ridiculous) between each major Nintendo first party releases. In the wiiU and 3ds days, it was almost always the case of when there was nothing to play on wiiU, something would release on 3DS and vice-versa which in the end means more money for Nintendo. Not to mention, a budget handheld device would almost certainly sell very well for them.
