If next year (in summer or winter) the stronger/better "switch"-hardware appears, bigger games with impressive graphics are possible then - i think. The official announcement will be in june directly from Japan or at E3-time.
But only if the big developers want it - I'm skeptical, the situation reminds me a little bit of the wii/u-time. I personally want games from the big developers and no (old) ports by other teams.
