It won't. The currently situation for the handheld market is Switch or nothing. If people want a handheld, they will buy whatever is available they won't just stop gaming and wait. And this is considering demand for Switch is small: It's not, it's crazy high. Why would demand for a hot product decrease if you just don't have any other option left? 

Yeah we already got that sentiment from your first comment, followed by the other comment you made on one of the articles.

We get it, you think it's gonna die, Valve are shit and will never support anything ever. 

Never said Valve was shit. Don't put words in people's mouths. Don't like a post then move on.

You guys remember those rumours about Switch Pro?

I Remember how a user said a company might have payed news sites to push those fake rumours, to sabotage for Nintendo. Sabotage as in, fans would be dissapointent If it wasn’t true.
Few days ago valve announced steam deck, a powerful handheld gaming device, a week after Nintendo oled was announced. When the dissapointment was still fresh among fans.

Those dissapointed people now flock to pre order steam deck. And call it, ”what a Switch pro should have been”.
Valve is rich enough to pay several big news sites like Bloomberg to push those fake rumours.
First i thought Sony may have done that. But now it seems more likey that was Valve.
Prestigous tech news sites don’t create fake hardware rumours, it damages their reliability, UNLESS they were payed a hefty sum by one of the richest gaming companies in the market.

Or

Im totaly wrong and no company payed for those fake rumours and news sites genuinly want ppl to distrust them

The Steam Deck addresses a different audience, is more expensive, has a shorter battery life, is heavier and storage is limited unless you buy the extra expensive model and even then games take more space than on the Switch because they won't be optimised for the Steam Deck. Also the Switch is generally more convenient because you don't need to do stuff like install Windows and you know exactly that all games available are able to run on the system, what isn't necessarily the case with the Steam Deck.

The most powerfull handheld was always the least selling. The Steam Deck having high specs doesn't mean anything. It's been said over and over again: the Atari Lynx and Game Gear were destroyed by the Game Boy, the PSP sold just over half of what the DS sold, the Vita was destroyed by the 3DS. It's always "OMG we have the highest specs!" and then they fail. Same with home consoles except for the PS4.

Handheld gamers don't care about specs.

It won't have any impact on the Switch whatsoever.

Bold: As if this has any meaning.

People still use IGN?

Moreover, they didn't hurt them despite being there to directly compete with them, which is not the case of the valve handheld.

You made two doom and gloom posts bud, no need to put words in your ,outh when you're doing it for me. 

Don't like it, don't comment and move on. Practice what you preach. 

No one was talking to you. You quoted me. I never spoke to you. I never said Valve sucked. It's just people should keep their expectations in check. You got offended. Poor you. Who cares. Valve has a history of bad hardware support. That's a statement of fact not dooming. Sorry your feelings got hurt over plastic.
